Answer: B) 1 Calorie

Explanation: The heat required to raise the temperature of 1 gram of a substance by 1 degree C is known as its specific heat capacity.

Specific heat capacity of water is \frac{4.184Joule}{g*0_C} and we know that, 4.184 Joule = 1 Calorie

So, specific heat capacity of water is \frac{1Calorie}{g*0_C} and hence the correct choice is B.

Explain the difference between an ignition transformer and a solid-state igniter
bazaltina [42]

Ignition transformer

1.      Weight of the transformer is more.

2.      Voltage output of the transformer is from 10,000 volts to 14,000 volts.

3.      Due to lower voltage output, fuel vaporization and ignition will be slow.

4.      When there is a drop in voltage supply, the transformer gets affected.

5.      Consumption of electricity is more.

 

Solid state igniter.

1.      Igniter weighs very light

2.      Igniter giver voltage output in the range of 14,000 volts to 20,000 volts

3.      Higher voltage output leads to faster vaporization of fuel and ignition

4.      Very small affect is observed when there is a voltage drop.

5.      Less electricity is consumed.

How many atoms are in 9.008 mol of Carbon? 0.7500 atoms 1.332 atoms 5.423 x 10^24 atoms 1.496 x 10^ -23 atoms
Zanzabum

 The number  of atoms that are  in 9.008   moles of carbon is

5.423 x 10^24 atoms


<u><em>calculation</em></u>

The  number of atoms is calculated using the Avogadro's   constant

That is   According to  Avogadro's   1  moles  = 6.02 x 10^23  atoms

                                                         9.008  moles= ? atoms

by cross multiplication

= [(9.008  moles x 6.02 x 10^23 atoms)  / 1  mole] = 5.423 x10^24 atoms

I need help fast please <br> What is ATP?
Jobisdone [24]

Answer:

Adenosine triphosphate is a complex organic chemical that provides energy to drive many processes in living cells, e.g. muscle contraction, nerve impulse propagation, and chemical synthesis. Found in all forms of life, ATP is often referred to as the "molecular unit of currency" of intracellular energy transfer. Wikipedia

A sample of a compound made entirely from copper and oxygen was found to have a total mass of 0.143 g the mass of copper in the
tensa zangetsu [6.8K]

Mass of Oxygen: 0.0159 grams

Moles of Oxygen: 9.94x10^-4

To find the mass of oxygen, subtract the mass of copper from the total mass.

0.143-0.1271=0.0159

There are 0.0159 grams of Oxygen.

To find how many moles there are, divide the given amount of oxygen by the molar mass (atomic mass) of oxygen because that mass is the same as one mole of oxygen.

Molar mass of Oxygen: 16.00

0.0159/16.00=9.94*10^{-4}

There are 9.94*10^-4 moles of Oxygen.
