Calcium nitrate reacts with sodium phosphate to form sodium nitrate and calcium phosphate. Given 96.1 grams of calcium nitrate w
Bingel [31]
Equation is:

Ca(NO3)2 + Na3PO4 —> NaNO3 + Ca3(PO4)2

Balance it out

3Ca(NO3)2 + 2Na3PO4 —> 6NaNO3 + Ca3(PO4)2

You have 96.1g of Calcium Nitrate

Moles = Mass/Molar Mass

Molar mass of Calcium Nitrate is 164.088 g/mol

96.1g / 164.088 g/mol =0.586 moles

Mole ratio is 3:1

Therefore 0.586/3 moles of calcium phosphate

Moles x molar mass = mass

0.586/3 x 310.18 g/mol = 60.6~g roughly as theoretical yield

If you had 1.00 kg of each kind of hardware, how many boxes of each would you<br> have?
dusya [7]

The number of boxes is calculated by dividing the

total mass of hardware boxes by 1.00 kg

<h3>What is a hardware?</h3>

A hardware is a physical component of a system that can be touched and felt.

Because hardware are physical components, they always have a given mass.

Assuming, several hardware each of mass 1.00 kg is available to be chosen from.

Also, assuming that the sum total of the mass of all the hardware is known.

The number of boxes can be calculated as follows:

  • total mass of hardware/1.00 kg

Therefore, the number of boxes is obtained by dividing the sum of the mass of the boxes by 1.00 kg.

When looking at Newman projections are there instances where the staggered confirmation is not the lowest in energy? Explain you
stiks02 [169]

Answer:

let's summarize the caution as we are given with human projection. We have to tell them stances where staggered confirmation is not the lowest in energy. Okay, so let's see that. Are there any instances that which conforms tiger is not the lowest energy. Okay, so the lowest energy is what then happened? The lowest in energy already happens on living. Honestly, when, when it happens the lowest in energy only happens when the bulky groups are at 1 80 degree with each other. When it happens when bulky, bulky, bulky groups are at 1 80 degree. Okay, When they are, for example, when the bulky groups are in this way At 180°, then it is Louis Why? Because repulsion are very less repulsion very less. Got it. So we have to tell when it is not the lowest so far not the lowest instance. These bulky groups should be together. So if they either make of angle of 60° or 300° together, suppose this is a bulky group one and this is a bulky group two and okay, so if it makes a 60 degree or 300 degree then this um have the highest energy Or has the energy is not lowest in it. Why? It is not lowest in it Because at 300° or 60°. Why? Because the pulsations are very high repulsion. Are you ready? Hi. So by looking at the humans projection we can conclude that when the if the bulky group parrot 1, 80 degree be considered as the lowest energy. And if they are at 300 or 60 degree or close to each other, republicans are higher and they are not in lowest energy.
