Becquerel  did not discover that the amount of exposure on the paper was proportional to the amount of uranium that was present in the rocks

The phenomenon of radioactivity was discovered by the French scientist Henri Becquerel in 1896 when he placed photographic paper in a drawer with some radioactive rocks.

We have to note that Becquerel did not discover that the amount of exposure on the paper was proportional to the amount of uranium that was present in the rocks hence the stetement is false.

Answer:

The water in the hydrate (referred to as "water of hydration") can be removed by heating the hydrate. When all hydrating water is removed, the material is said to be anhydrous and is referred to as an anhydrate.

Explanation:

If the water is not completely removed from salt during heating process it will result in higher mole ratio of water to salt as mass of water will also be accounted while calculating mole ratio.

Salt is defined as a chemical compound which is ionic in nature and consists of cation and an anion.It has no net electrical charge as the charges are completely neutralized in case of salts.

They are classified as acidic, basic or neutral salts depending on the ions they produce on dissolution.They have wide variety of colors depending on the elements from which they are formed and have five basic tastes.Salts are usually odorless  except a few exceptions . They are highly soluble in water and are insulators in the solid state, to make them conductive they need to be melted or dissolved.

Because we already know that sodium oxide is a binary ionic compound because it contains one metal cation and one non-metal anion.

Answer:

D. Na2O

Explanation:

Sodium oxide (Na2O) is an ionic compound. Its constituent atoms are, respectively, a metal and a non-metal.

Sodium (Na), as a metal, will attempt to lose electrons to reach an octet state. Oxygen (O2), as a non-metal, will attempt to gain electrons to reach an octet state.

Answer:

386.75 grams

Explanation:

You can use dimensional analysis to help you solve for this question

1. set up a proportion

                          x grams

4.25 mol x        x mole

2. to find the amount of grams/mol that are in NiS we find the gram formula mass (mass of all the atomic masses of each element)

Ni- 59 grams

S- 32 grams

add these together and you get 91 g/mol

3. now plug in the values and multiply across

                    91 grams

4.25 mol x     1 mole

when you multiply across this is equal to 386.75 grams

For a (unbalanced) reaction: NaOH +CO2-Na2CO3 + H2O, the moles of NaOH and moles of each product are formed are mathematically given as

a) Moles of NaOH =44.05

b)   Moles of Na2CO3=21.0

Generally, the equation for the Chemical reaction  is mathematically given as

2 NaOH(aq)+ CO2(g)------> Na2CO3(aq)+ H2O(l)

Therefore

Moles of CO2= 925/44

Moles of CO2=21.0

Hence

Moles of NaOH = 2 x Moles of CO2

Moles of NaOH = 2x925/44

Moles of NaOH =44.05

In conclusion

Moles of Na2CO3 925/44

Moles of Na2CO3=21.0

And

Moles of H2O= 925/44

Moles of H2O= 21.0

Answer:

The molecules are held together by intermolecular force of attraction. More the force the fusion takes after some time only that means the melting point is high. So molecules with greater molecular forces have high melting point and less molecular forces have low melting point.

Answer:

On heating a solid, the kinetic energy of the particle increases. The particle start vibrating with greater speed. The energy supplies by heat overcomes the force of attraction between the particles.

If this force of attraction is more, then more heat energy will be necessary to overcome this force. So, the melting point of the solid will be higher.

Answer:

About 0.164 g of glucose.

Explanation:

We can determine the mass of glucose produced given the volume of oxygen gas produced with stoichiometry.

Recall that at STP, a mole of any gas occupies a volume of 22.4 L.

From the reaction, six moles of oxygen gas is produced for every one mole of glucose.

Lastly, the molecular weight of glucose is 180.18 g/mol.

Therefore:
[tex]\displaystyle \begin{aligned} 122\text{ mL O$_2$} & \cdot \frac{1\text{ L O$_2$}}{1000\text{ mL O$_2$}}\cdot \frac{1\text{ mol O$_2$}}{22.4\text{ L O$_2$}} \cdot \frac{1\text{ mol C$_6$H$_{12}$O$_6$}}{6\text{ mol O$_2$}} \cdot \frac{180.18\text{ g C$_6$H$_{12}$O$_6$}}{1\text{ mol C$_6$H$_{12}$O$_6$}} \\ \\ & = 0.164\text{ g C$_6$H$_{12}$O$_6$}} \end{aligned}[/tex]

Therefore, about 0.164 g of glucose is produced.

The combination of glue and water creates a physical change rather than a chemical change.

Physical changes are changes to the physical properties of materials and are usually reversible.

Chemical changes, on the other hand, are changes to the chemical properties of materials and are usually irreversible.

Mixing water with glue will only result in the glue being diluted with water and creates no chemical reaction. The glue can be recovered by distilling off the water.

Thus, mixing glues with water is only a physical change as the chemical properties of the glue remain intact.

.75 + .25 + 1.25 = 2.25 atm

1 atm is 760 mm hg

2.25 * 760 = 1710 mm HG

Answer:

[tex]\huge\boxed{\sf 2.25\ atm = 1710\ mm\ of\ Hg}[/tex]

Explanation:

Partial pressure of gas A = 0.75 atm

Partial pressure of gas B = 0.25 atm

Partial pressure of gas C = 1.25 atm

Total partial pressure = 0.75 atm + 0.25 atm + 1.25 atm

= 2.25 atm

We know that:

1 atm = 760 mm of Hg

Multiply 2.25 to both sides

2.25 atm  = 760 × 2.25 mm of Hg

2.25 atm = 1710 mm of Hg
