Answer:

32000atm

Explanation:

Using Boyle's law equation;

P1V1 = P2V2

Where;

P1 = initial pressure (atm)

P2 = final pressure (atm)

V1 = initial volume (

V2 = final volume (L)

According to the question below:

P1 = 160.0 atm

P2 = 3.0 atm

V1 = 600L

V2 = ?

Using P1V1 = P2V2

160 × 600 = 3 × V2

96000 = 3V2

V2 = 96000/3

V2 = 32000atm

Which of the following specifies the correct reducing agent in the given redox reaction? View Available Hint(s) Which of the fol

padilas [110]

Answer: $NiO+CO\rightarrow Ni+CO_2$ : reducing agent is CO.

Explanation:

a) $Fe+Cu^{2+}\rightarrow Fe^{2+}+Cu$

The oxidation state of copper reduces from +2 to 0, it is getting reduced. As $Cu^{2+}$ gets reduced, it acts as an oxidising agent.

The oxidation state of iron increases from 0 to +2. Thus, it is getting oxidized. As $Fe$ gets oxidized, it acts as a reducing agent.

b. $2Na+Cl_2\rightarrow 2NaCl$

The oxidation state of chlorine reduces from 0 to -1, it is getting reduced. As $Cl_2$ gets reduced, it acts as an oxidising agent.

The oxidation state of sodium increases from 0 to +1. Thus, it is getting oxidized. As $Na$ gets oxidized, it acts as a reducing agent.

c. $C+O_2\rightarrow CO_2$

The oxidation state of oxygen reduces from 0 to -2, it is getting reduced. As $O_2$ gets reduced, it acts as an oxidising agent.

The oxidation state of carbon increases from 0 to +2. Thus, it is getting oxidized. As $C$ gets oxidized, it acts as a reducing agent.

d. $NiO+CO\rightarrow Ni+CO_2$

The oxidation state of nickel reduces from +2 to 0, it is getting reduced. As $Ni^{2+}$ gets reduced, it acts as an oxidising agent.

The oxidation state of carbon increases from +2 to +4. Thus, it is getting oxidized. As $CO$ gets oxidized, it acts as a reducing agent.

A woman with diagnosed osteoporosis is told by her doctor to take 1,000 mg of calcium carbonate in addition to increasing intake

spayn [35]

Answer:

400 mg

Explanation:

Given:

A woman with is told by her doctor to take 1,000 mg of calcium carbonate.

Question asked:

How many mg of calcium are in this 1,000 mg regimen of calcium carbonate?

Solution:

As we know:

<em>Amount of elemental calcium in a medicine containing calcium carbonate = 40%</em>

As here doctor prescribed 1000 mg of calcium carbonate to be taken by the woman increasing intake of calcium-containing foods in her diet and including regular weight-bearing exercise, hence amount of elemental calcium in 1,000 mg regimen of calcium carbonate will be,

$40\%\ of\ 1000\ mg\\\frac{40}{100} \times1000\ mg\\\frac{40000}{100} = 400\ mg$

Therefore, 400 mg of calcium are in this 1,000 mg regimen of calcium carbonate.
