Consider the reaction cacn2 3 h2o → caco3 2 nh3 . how much nh3 is produced if 187 g of caco3 are produced?
shusha [124]
B ase from the reaction <span>cacn2 3 h2o → caco3 2 nh3, for every 1 mole of caco3 produced there 2 moles of nh3 being produced. to solved this, we must first convert the caco3 to moles.

mass nh3 = 187 g caco3 (1 mol caco3 / 100 g caco3 ) ( 2 mol nh3 / 1 mol caco3) ( 17 g nh3 / 1 mol nh3)

mass nh3 = 63.58 g nh3 is produced</span>

Consent bonds exist when combining atoms give up or accept electrons true or false
prohojiy [21]
I think the "consent bonds" in your question is means covalent bond. It is false. Covalent bond share the electrons between atoms while ionic bond give up or accept electrons.

Which particle has a mass of approximately 1 atomic mass unit?
labwork [276]
The answer is D) a neutron.

When we say an atom's mass is, like 5 atomic mass units actually we are saying that the total number of the neutrons and protons in its nucleus is 5.

The mass of a neutron and a proton is each one atomic mass unit.

Mass of a neutron is approximately 1 atomic mass unit.

Which best explains why water is able to “stick” to the side of glass?
AveGali [126]

Explanation:

Adhesion means the ability to stick on the surface of another substance.

Water exhibits adhesive forces due to which it is able to stick to the glass.  Due to adhesive forces water spreads over the surface of glass and sticks to it.

These adhesive forces between the glass and water enough that it deforms the spherical shape of water molecules and help them stick to the surface of glass. As a result, adhesive forces overcome the repulsion between like molecules.

Hence, water is able to “stick” to the side of glass due to strong adhesive forces.

Microwave ovens work by irradiating food with microwaves, which are absorbed by the water molecules in the food and converted to
snow_tiger [21]

Answer:

7.45\times 10^{26} photons are emitted per second in a 1\times 10^3 Watt microwave oven.

Explanation:

The expression for the power is:-

Power=\frac{Energy}{Time}

Also, E=n\times \frac{h\times c}{\lambda}

Where,  

n = the number of photons

h =  Plank's constant having value 6.626\times 10^{-34}\ Js

c =  the speed of light having value 3\times 10^8\ m/s

\lambda = the wavelength of the light

So,  

Power=\frac{n}{Time}\times \frac{h\times c}{\lambda}

Thus, the expression for photons per second is:-

\frac{n}{Time}=\frac{Power\times \lambda}{h\times c}

Given that:-

Power = 10³ Watt

( 1 cm = 0.01 m)

[/tex]

So,  

Photon/sec=\frac{10^{3}\times 0.148}{6.626\times 10^{-34}\times 3\times 10^8}=7.45\times 10^{26}

7.45\times 10^{26} photons are emitted per second in a 1\times 10^3 Watt microwave oven.
