Which color marks the places on the map where the continental shelf is most likely found?

Answer:

Explanation:

All you need to know is the atomic mass of platinum, and Avogadro's number.

2.00g Pt divided by atomic mass gives you the moles of platinum, and multiplying by avogadro's number (6.022 x 10^23) gives you the number of atoms.

Atomic mass of platinum can be found on any periodic table.

Hope this helped.

12.04 × 10²³ number of platinum atoms are present in 2 grams of platinum.

To calculate the no. of atoms in any substance, we have to multiply the no. of moles of that substance by the Avogadro's no.

Value of Avogadro's no. = 6.022 × 10²³

We can calculate the mole by using the below formula:

n = W / M, where,

n = no. of moles

W = given mass = 2.00g

M = molar mass or atomic mass = 195.09 g/mol

n = 2 / 195.08 = 0.0102 mol

Number of atoms in 2.00g of platinum = 2 × 6.022 × 10²³ = 12.04 × 10²³.

Hence, number of atoms that are present in 2.00g of platinum is 12.04 × 10²³.

What is Charge ?

Charge is a basic property of matter that is associated with the presence or absence of electrons. Objects can have positive or negative charge, or they can be neutral, which means they have an equal number of positive and negative charges. In physics, charge is one of the fundamental concepts used to explain the behavior of matter and energy in the universe. The interaction between charges is described by Coulomb's law, which states that the force between two charges is proportional to the product of their charges and inversely proportional to the square of the distance between them.

This is the balanced reaction equation for the combustion of methane.

Explanation:

The Law of Conservation of Mass basically states that matter can neither be created nor destroyed. As such, we must be able to show this in our chemical reaction equations.

If you look at the equation above, you'll see an arrow that separates the reaction equation into two parts. This represents the direction of the reaction.

To the left of the arrow, we have our reactants.

To the right of the arrow, we have our products.

The quantity of each individual element in the left must equal the quantity of each individual element in the right.

So if you look below, you'll see the unbalanced equation, and I'll try to explain how to balance the reaction.

Our next step is to break these down into individual atoms.

We have:

If you're confused by this, look to see the little number to the bottom right of each element, the subscript, and it tells you how many of each atom are in the molecule. Make sense?

Now we look to the other side of the equation.

Here we see our products are

Again, we break these down into individual atoms again.

We have:

Answer:

mass of 1 mole of 34.4liters, O2, STP = 95.039999g

Explanation:

Write the problem as a mathematical expression.

Find the mass in 34.4liters of O2 gas at  STP

To find the mass of 1 mole of 34.4liters, O2, STP look up the atomic mass of each element and multiply it by the number of atoms contained in each element in the molecule.  

mass of 1 mole of 34.4liters, O2, STP = 2(mass of O) + (mass of S) + (mass of T) + (mass of P)

Fill in the atomic masses from the periodic table.

mass of 1 mole of 34.4liters, O2, STP = 2(16) + (32.06999969) + (0) + (30.96999931)

Simplify the result.

mass of 1 mole of 34.4liters, O2, STP = 95.039999g

Answer:

the answer is Covalent compounds separate into neutral molecules when they dissolve in water.

Explanation: covalent doesn’t conduct electricity in water

The common salt transforms the distilled water into an electrical conductor. But sugar molecule is a covalent compound which dissolve in water. So the white sugar does not show any conductivity.

The electrical conductors are defined as the materials which allow electricity to flow through them easily. The property of conductors which allow them to conduct electricity is defined as the conductivity. The metals are good conductors of electricity.

The distilled water does not contain any contaminants and it is incapable of conducting even very minute amount of electricity. But during the addition of ordinary salt or sodium chloride to the distilled water, it becomes electrically conductible.

The presence of chlorine and sodium ions makes the distilled water to conduct electricity. Here sugar is a covalent compound which separate into neutral molecules when they dissolve in water. So covalent compounds does not conduct electricity.

Explanation:

We were told that one of two different oxidizing agents were used H2CrO4 and H2SO4 or PCC/CH2Cl2.

Now, we must know that when we use H2CrO4 and H2SO4, primary alcohols are converted to aldehydes and then to carboxylic acids while secondary alcohols are converted to ketones.

When we use PCC/CH2Cl2 primary alcohols are converted to aldehydes and does not move further to convert to carboxylic acids while secondary alcohols are converted to ketones.

Recall that tertiary alcohols are not oxidized at all.

Answer:

5.88 dL = 0.588 litre

Explanation:

We need to find a conversion from 5.88 dL to liters.

We know that the conversion is as follows :

1 deciliter = 0.1 litre

To find 5.88 dL to liters, we use the unitary method. So,

5.88 dL= (0.1×5.88) litre

5.88 dL = 0.588 litre

So, there are 0.588 liters in 5.88 dL.
