How many miles of MgCI2 are there in 339g of compound?

Physics
1 answer:
harkovskaia [24]3 years ago
4 0

I'm going to answer this by using rounded numbers for the atomic masses. You need only go back and put the numbers in from your periodic table. My answers will be close, but not what you should get.

Find the Molar Mass of MgCl2

Mg =                   24 grams

2Cl = 2 * 35.5 = 71 grams

Total  =              95 grams

Find the mols in 339 grams

1 mole = 95 grams

x mol = 339

Solve

339 = 95x   Divide by 95

339/95 = x

x = 3.67 mols  Answer

Julia walks from the park, which is six blocks east of her house, to the store, which is three blocks east of her house. Julia walks for 5 minutes. This walk's average speed will be 1.2 blocks per minute. Option B is correct.

<h3>What is displacement?</h3>

Displacement is defined as the shortest distance between the two points. Distance is the horizontal length covered by the body. While displacement is the shortest distance between the two points.

Displacement is a vector quantity .its unit is m.

The average velocity on this walk will be;

\rm v_{avg}= \frac{d}{t} \\\\ \rm v_{avg}= \frac{6 \ block+ 3 \ block }{5 \ minute } \\\\ v_{avg}=1.4  \ block /min

Hence option B is correct.

Q.01 When charging a secondary cell, energy is stored within a dielectric material using an electric field. True or False
Nitella [24]

True, when charging a secondary cell, energy can be stored within a dielectric material using an electric field.

<h3>Relationship between dielectric material and electric field</h3>

The electric field in a capacitor separates the negative and positive charges in the dielectric material, this causes an attractive force between each plate and the dielectric.

The dielectric material can store electric energy due to its polarization in the presence of external electric field, which causes the positive charge to store on one electrode and negative charge on the other.

Thus, when charging a secondary cell, energy can be stored within a dielectric material using an electric field.

Select all that apply. Select the items that describe an economy at equilibrium.
ella [17]

The correct answers are:

B) Producers supply enough goods for consumers;

D) Supply equals demand;

In the economics, the equilibrium state basically means that the supply in the market is well balanced with the demand on the market, thus leading to an ideal economic state within the economy. The equilibrium will essentially mean that the supply is equal to the demand, thus there will be maximum efficiency. Also, since the producers are managing to supply just the right amount of goods to the consumers, everyone will benefit, with the consumers always have what they want, and the producers always have all of their products sold.
