Answer:

chemical

Creatine Phosphate (with oxygen) So all muscle cells contain a high-energy compound called creatine phosphate which is broken down to make more ATP quickly. Creatine phosphate can supply the energy needs of a working muscle at a very high rate, but only for about 8–10 seconds.adenosine triphosphate (ATP)

The source of energy that is used to power the movement of contraction in working muscles is adenosine triphosphate (ATP) – the body's biochemical way to store and transport energy. However, ATP is not stored to a great extent in cells

The volume of copper : 3.24 ml

Density is a quantity derived from the mass and volume

Density is the ratio of mass per unit volume

With the same mass, the volume of objects that have a high density will be smaller than objects with a smaller type of mass

The unit of density can be expressed in g/cm³ or kg/m³

Density formula:

[tex]\large{\boxed {\bold {\rho~=~ \frac {m} {V}}}}[/tex]

ρ = density , g/cm³ or kg/m³

m = mass , g or kg

v = volume , cm³  or m³

A common example is the water density of 1 gr / cm³

The density of copper : 8.96 gr/ml

mass of copper : 29 g

then the volume :

[tex]\tt V=\dfrac{m}{\rho}\\\\V=\dfrac{29~g}{8.96~g/ml}\\\\V=\boxed{\bold{3.24~ml~or~3.24~cm^3}}[/tex]

Answer:

Density = (3.33kg or g)/cm³(since you didn't state the unit of the mass)

Explanation:

volume = length × breath × height

let's take it as,

length = 2.0cm

breath = 3.0 cm

height = 2.0 cm

mass = 40 kg or g (since you didn't state the unit of the mass)

volume = ?

volume = length × breath × height

volume = (2 × 3 × 2)cm

volume = 12 cm³

Density = mass /volume

40kg or g/12cm³

Density = (3.33kg or g)/cm³(since you didn't state the unit of the mass)

Explanation:

the pair of opposite but equal forces that two objects exert on each other. weight. the gravitational force exerted by a large body, usually Earth, on an object.

Answer:

exerted forces

Explanation:When an object has several forces acting on it, the effects of force is same as one force acting on the object in a certain direction and this overall force is called the ‘resultant force’.

The two chemical elements that are most likely to bond with each other are: C. Chlorine and Calcium.

A chemical bond refers to the forces of attraction existing between ions, crystals, atoms or molecules and that are typically responsible for the formation of new chemical compounds.

In Chemistry, there are three (3) main types of chemical bonds and these are:

I. Hydrogen bonds.

II. Covalent bonds.

III. Ionic bonds.

An ionic bond can be defined as a chemical bond which involves a metallic element transferring one or more electrons to a non-metallic element.

In this scenario, the element Chlorine which have seven valence electrons would accept an electron from Calcium (Alkali metal) to form a chemical compound called calcium chloride.

In conclusion, two chemical elements that are most likely to bond with each other by forming an ionic bond are Chlorine and Calcium.

Answer:

A

Explanation:

Based on the observation that trichloromethane (chloroform) and water can be separated using a separating funnel, the conclusion that can be made from this observation alone is:

E. Trichloromethane and water do not mix.

When two substances are immiscible, such as trichloromethane (chloroform) and water, it means that they do not dissolve or form a homogeneous mixture when combined. Instead, they form separate layers within the mixture.

The immiscibility between trichloromethane and water is primarily due to their different polarities and intermolecular forces. Trichloromethane is a nonpolar compound with relatively weak intermolecular forces, while water is a highly polar compound with strong intermolecular forces.

Water is a polar molecule due to its bent shape and the presence of electronegative oxygen atoms that create partial positive and negative charges. Trichloromethane, on the other hand, is a symmetrical molecule with four chlorine atoms surrounding a central carbon atom, resulting in a nonpolar distribution of charge.

The fact that these two substances can be separated using a separating funnel indicates that they are immiscible, meaning they do not mix or dissolve in each other to form a homogeneous solution. Trichloromethane and water have different polarities and intermolecular forces, causing them to form separate layers in the separating funnel.

how many Helium and oxygen molecules = H2O = + O2

Answer:

Explanation:

The density of a substance can be found by using the formula

[tex]density = \frac{mass}{volume} \\[/tex]

From the question

mass = 10 g

volume = final volume of water - initial volume of water

volume = 52.1 - 50.7 = 1.4 mL

We have

Answer:

Various compounds made of different forces between molecules

Explanation:

In an experiment, the independent variable is the variable that is changed or manipulated by the experimenter in order to effect a measurable response.

According to this question, a student compares the boiling point of substances having different intermolecular forces. This means that the student uses different substances with different intermolecular forces and measures the boiling point of each, which depends on the intermolecular forced in them. Hence, the independent variable in this experiment is the VARIOUS COMPOUNDS MADE OF DIFFERENT FORCES BETWEEN MOLECULES.

i think with exothermic reactions heat is released

this is what i looked up

hope this helps i took chem last year and think this is what i learned

Considering the definition of exothermic and endothermic reactions, the correct answer is second option: the reaction is endothermic.

Energy is the ability to do work or to produce heat.

Remembering that chemical reactions involve a reorganization of atoms between substances with breaking or formation of chemical bonds, this formation or breaking of chemical bonds is accompanied by changes in the energy of the system.

Chemical reactions that release heat are called exothermic. That is, an exothermic reaction is one where energy flows out of the system.

So, at room temperature, the heat released by a chemical reaction is enough to cause a rise in temperature.

An endothermic reaction is one that requires heat to take place. In other words, a chemical reaction is endothermic when it absorbs energy from the environment.

In this case, the heat is transferred from the outside to the inside of the system. By absorbing heat, the effect of an endothermic reaction is to lower the temperature.

When ammonium chloride is dissolved in water, the beaker gets cold. That means the system is absorbing heat from the surrounding and the temperature does down.

So, the correct answer is second option: the reaction is endothermic.
