Shaun's doctor has recommended that he consume 200 calories of protein a day. Shaun consumed 176 calories of protein in one day.

evablogger [386]

Answer: Shaun must consume 6 more g of protein to reach the required amount.

Explanation:

Given : Recommended amount of protein = 200 calories

Now 4 calories = 1 gram of protein

Thus 200 calories = $\frac{1}{4}\times 200=50$ g of protein.

Calories consumed per day by Shaun = 176 calories

176 calories = $\frac{1}{4}\times 176=44$ g of protein.

Thus Shaun need to consume = (50-44) g = 6 of protein to reach the required amount.

Shaun must consume 6 more g of protein to reach the required amount.

What is the radioactivity of the sample of sodium -24 after 30h?

statuscvo [17]

Half life is 15 hours
so 30 hours would be 2 half lives

after 15 hours it would be at 50%
after 15 more hours it would be at 50% of 50%

so .5 x .5 = .25

it would be 25%

What is the effect of decreasing the volume of the reaction mixture? What is the effect of decreasing the volume of the reaction

fgiga [73]

Answer:

By decreasing the volume, the equilibrium will shift to the side with the smallest amount of particles

Explanation:

Step 1: Data given

The principle of Le Chatelier says:

When the volume is decreased, the equilibrium will shift to the side of the smallest number of particles.

2NOBr(g) ⇌ 2NO(g)+Br2(g)

In the following example, we have 2 moles of NOBr (on the left side) and 3 moles of gas on the right side. This means the left side, the reactant side, has the smallest number of particles.

The equilibrium will here shift to the left side, the side of NOBr.

In the following example

2NO2(g) ⇌ N2O4(g)

We have 2moles of NO2 on the left side and 1 mol of N2O4 on the right side.

By decreasing the volume, the equilibrium will shift to the side of the smallest number of moles. Here this is the right side, the side of N2O4.

What is the most stable monatomic ion formed from lithium?

s344n2d4d5 [400]

<u>Answer:</u> The ion formed by lithium element is $Li^+$

<u>Explanation:</u>

Ions are formed when an atom looses or gains electrons.

If an atom gains electrons, it leads to the formation of negative ions known as anions. For Example: Fluorine gains 1 electron to form $F^-$ ions.

If an atom looses electrons, it leads to the formation of positive ions known as cations. For Example: Sodium looses 1 electron to form $Na^+$ ions.

Lithium is the 3rd element of the periodic table having 3 electrons.

The electronic configuration of lithium element = $1s^22s^1$

This element will loose 1 electron to attain stable electronic configuration and will lead to the formation of $Li^+$ ion.

Hence, the ion formed by lithium element is $Li^+$
