Find the mass of 1.25 moles Ca(OH)2.​

Answers

Answer :
92.5
Explanation
1.25 x 74= 92.5g

According to the mole concept, the mass  of 1.25 moles Ca(OH)₂ is 92.61 grams.

What is a mole?

Mole is defined as the unit of amount of substance . It is the quantity measure of amount of substance of how many elementary particles are present in a given substance.

It is defined as exactly 6.022×10²³ elementary entities. The elementary entity can be a molecule, atom ion depending on the type of substance. Amount of elementary entities in a mole is called as Avogadro's number.

It is widely used in chemistry as a suitable way for expressing amounts of reactants and products.For the practical purposes, mass of one mole of compound in grams is approximately equal to mass of one molecule of compound measured in Daltons. Molar mass has units of gram per mole . In case of molecules, where molar mass  in grams present in one mole  of atoms is its atomic mass.Mass=number of moles×molar mass=1.25×74.09=92.61 g.

Thus,the mass  of 1.25 moles Ca(OH)₂ is 92.61 grams.

This is for my wonderful boy friend Putting my defenses up
'Cause I don't wanna fall in love
If I ever did that, I think I'd have a heart attack
Never put my love out on the line
Never said "Yes" to the right guy
Never had trouble getting what I want
But when it comes to you, I'm never good enough
When I don't care, I can play 'em like a Ken doll
Won't wash my hair, then make 'em bounce like a basketball
But you make me wanna act like a girl
Paint my nails and wear high heels, yes, you
Make me so nervous that I just can't hold your hand
You make me glow
But I cover up, won't let it show
So I'm putting my defenses up
'Cause I don't wanna fall in love
If I ever did that, I think I'd have a heart attack
I think I'd have a heart attack
I think I'd have a heart attack
Never break a sweat for the other guys
When you come around, I get paralyzed
And every time I try to be myself
It comes out wrong like a cry for help
It's just not fair; pain's more trouble than love is worth
I gasp for air; it feels so good, but you know it hurts
But you make me wanna act like a girl
Paint my nails and wear perfume for you
Make me so nervous that I just can't hold your hand
You make me glow
But I cover up, won't let it show
So I'm putting my defenses up
'Cause I don't wanna fall in love
If I ever did that, I think I'd have a heart attack
I think I'd have a heart attack
I think I'd have a heart attack
The feelings got lost in my lungs
They're burning I'd rather be numb
And there's no one else to blame
So scared I take off, and I run
I'm flying too close to the sun
And I burst into fla-fla-flames
You make me glow
But I cover up, won't let it show
So I'm putting my defenses up
'Cause I don't wanna fall in love
If I ever did that, I think I'd have a heart attack
I think I'd have a heart attack (Heart attack)
I think I'd have a heart attack

how many significant figures are needed in the answer when 1.31m is multiplied by 6.5 m​

Answers

Answer:

two

Explanation:

The number of significant figures needed in the answer is 2.

This is because when finding the products of two numbers, the result is as accurate as the least number of significant figures of the numbers being multiplied.

Here the numbers being multiplied are;

 1.31m

 6.5m

        1.31m has 3 significant figures

          6.5m has 2 significant figures.

So, the product will have 2 significant figures

Adding electrons creates an ion that is larger then the neutral atom; removing electrons produces an ion that is smaller then the neutral atom. When electrons are added, mutual repulsions push them apart and they occupy a larger volume so the ion increases in size.

Until well in the 60ties, the luminous dials of wrist watches and alarm clocks were marked with luminous paints containing Radium (Ra-226) or Promethium (Pm-147). These kind of watches are no longer manufactured today. This is not due to the radiation exposure to the persons wearing the watches but because of the radiological risk for the persons manufacturing them.

Freezing decreases salinity, while melting increases salinity.


Both freezing and melting increase salinity.

Answers

Answer:

For every 5 psu increase in salinity, the freezing point decreases by 0.28 degrees Celsius (0.5 degrees Fahrenheit); thus, in polar regions with an ocean salinity of about 32 psu, the water begins to freeze at -1.8 degrees Celsius (28.8 degrees Fahrenheit).

A process that releases heat, such as freezing or condensation is called?

Answers

Answer:

exothermic

Explanation:

An exothermic reaction gives off heat energy. Condensation is the process by which water vapor turns into liquid water. This typically occurs when water vapor molecules come into contact with cooler molecules. This causes the water vapor molecules to lose some energy as heat which is a exothermic reaction.

When water becomes a solid, it releases heat, warming up its surroundings. This makes freezing an exothermic reaction.

What is the overall reaction equation

Answers

Answer:

If m or n is zero, the reaction is zero order in A or B, respectively, and the rate of the reaction is not affected by the concentration of that reactant. The overall reaction order is the sum of the orders with respect to each reactant. If m = 1 and n = 1, the overall order of the reaction is second order

(m + n = 1 + 1 = 2).
