Answer:
To find the number of electrons an atom has, start by looking up the element you're working with on the periodic table and locating its atomic number, which will be in the upper left-hand corner of the square. Then, identify the charge of the ion, which will be written as a superscript to the right of the element.
Hope this helps!

) During a 56-week test, 3,731 patients participated in the double-blind trial. participants did not have type 2 diabetesmellitus. one group of participants received once-daily subcutaneous injections of liraglutide at a dose of 3.0 mg. The other participants received a placebo. Both groups received counseling on lifestyle modification. At the end of the 56 weeks, the bodyweight of each participant was determined. Which of the following best the question that was being investigated in the study? a. Can body mass index affect the onset of diabetes? b. Is liraglutide effective for weight loss? c. What effect does Liraglutide have on diabetes? d. How does lifestyle modification counseling affect body weight?
Once identified the controlled, the independent, and the dependent variables, we can say the question is B) Is liraglutide effective for weight loss?
To answer this question, what we need to do first is to identify the variables involved in the experiment.
What are the variables involved in an experiment?Dependent variables
These are the variables whose response depends on any change in the independent variable.
Independent variablesThese are all the variables in an experiment that provoke a response in another variable. They are modified in the experiment to analyze how another variable responds to it.
Controlled variableControlled variables are kept constant in an experiment. Unlike the independent variable, the controlled variables do not influence the results. These variables do not affect the response of the dependent variable.
In this experiment we can also identify two groups. The experimental group and the control one. Both groups are composed of individuals coming from the same population.
What is the control group?The control group is used to identify any factors other than the modified variables of the treatment that might influence the results obtained in the study.
What is the experimental group?This group gets the treatment to observe how the independent variable affects the individuals.
In the experiment,
Control group ⇒ receives placeboExperimental group ⇒ receives liraglutideindependent variable ⇒ liraglutidecontrolled variables ⇒ lifestyle modification, participants did not have type 2 diabetes mellitus.dependent variable ⇒ bodyweight of each participantAccording to the identification of the variables, the question that was being investigated in the study is option B) Is liraglutide effective for weight loss?

with a population growth rate of 5% how long will it take for a population to double from 20,000 to 40,000 people?
Answer:
15 years
Explanation:
Compound growth
Equation:
20000 x 1.05 to the power of how ever many years needed
20000 x 1.05 to the power of 15 takes it just over, with 41578 people alongside decimals.
Therefore, it is 15 years.
Answer:

How many moles of LiCl are contained in 50.0 mL of 0.600 M solution?
Answer:
0.0300 moles LiCl
Explanation:
You can find the amount of moles using the molarity formula. The general structure looks like this:
Molar Concentration (M) = moles / volume (L)
You were given the molar concentration and volume in milliliters. Once you convert the volume to liters (by dividing by 1,000), substitute the values into the molarity formula. Then, you can simplify to find moles. The final answer should have 3 sig figs according to the given values.
50 mL / 1,000 = 0.0500 L
0.600 M = moles / 0.0500 L
(0.600 M) x (0.0500 L) = moles
0.0300 = moles

This may be because cats belong to the lion family, and they evolved to hunt their own prey.The fact that my cat has fast-growing nails that can be kept sharp is a physiological adaptation, which has helped cats scratch off predators and thus better their survival chances.
