True

Explanation:

When people conserve electricity, power plants do not need to produce as much electricity because there is less demand for it.

This very correct.

When electricity is used in a sustainable way, there is little of it consumed.
Switching off idle electronics would make that amount of electric current to be re-distributed to another place.
Less coal and fuel would be used and power plants do not need to produce as much electricity.
Most electricity produced in power plants are often wasted due to idle appliances consuming the bulk of them.
When these appliances are turned off, less energy is in demand and less will be produced.

A chemist wants to make 6.5 L of a .350M CaCl2 solution. What mass of CaCl2(in g) should the chemist use?

kotykmax [81]

First M stands for Molarity which is (moles of solute) / (Liters of solution). we also know that moles = (mass) / (molar mass). so we can form some equations here. We know:
Molarity (M) = moles (mol) / Liters (L)
moles (mol) = (mass) / (molar mass)

we can substitute the (mass) / (molar mass) for (moles) and get:
M = [(mass) / (molar mass)] / Liters

we can now isolate mass and get
M * Liters * molar mass = mass

now we need to find the molar mass of CaCl2 which is 110.98 g/mol

plug the values in and get
.350M * 6.5L * 110.98 g/mol = mass

mass = 252.4795g however the 6.5L has only 2 sig figs so i would say

mass CaCl2 = 2.5 * 10 ^2 g

Binary molecular (covalent) compounds are formed as the result of a reaction between two nonmetals. Although there are no ions i

ollegr [7]

Answer:

Binary molecular compounds are the compounds consisting of two non-metallic elements. Examples of binary molecular compounds include: NO2, HCl, HF, P2O5 e.t.c.

Rules For Naming Binary Molecular Compounds

Naming binary molecular compounds is quite easy,

1. The first element is given its name.

2. The second element is given its root name (such as, hydro, carb,ox, chlor e.t.c.) followed by suffix <em>ide.</em>

Name of N2O4 - Dinitrogen tetraoxide

Chemical Formula of;

iodic acid: HI

disulfur trioxide: S2O3

dinitrogen monoxide: N2O

hydrofluoric acid: HF

Difference between Binary acid and an oxyacid

An oxyacid is an acid consisting of an oxygen atom bonded to a hydrogen atom and at least one other non-metallic element. Examples of oxyacids include HNO3, H2SO4 e.t.c.

Binary acids are the acids consisting of hydrogen atom bonded to a non-metallic element. Examples include HF, HCl, HI e.t.c.

A sample of carbon dioxide gas occupies a volume of 250 mL at 25c what volume will it occupy at 95c

anzhelika [568]

Considering the Charles's law, the sample of carbon dioxide gas will occupy 308.72 mL.

<h3>Charles's law</h3>

Charles's law establishes the relationship between the temperature and the volume of a gas when the pressure is constant. This law says that the volume is directly proportional to the temperature of the gas: for a given sum of gas at constant pressure, as the temperature increases, the volume of the gas increases and as the temperature decreases, the volume of the gas decreases.

Mathematically, Charles's law states that the ratio between volume and temperature will always have the same value:

$\frac{V}{T} =k$

Considering an initial state 1 and a final state 2, it is fulfilled:

$\frac{V1}{T1} =\frac{V2}{T2}$

<h3>Final volume in this case</h3>

In this case, you know:

V1= 250 mL
T1= 25 C= 298 K (being 0 C=273 K)
V2= ?
T2= 95 C= 368 K

Replacing in Charles's law:

$\frac{250 mL}{298 K} =\frac{V2}{368 K}$

Solving:

$V2=368 K\frac{250 mL}{298 K}$

Finally, the sample of carbon dioxide gas will occupy 308.72 mL.
