Ammonium phosphate ((NH), PO) is an important ingredient in many fertilizers. It can be made by reacting phosphoric acid (TI,PO.

madreJ [45]

Answer:

22.35 g of (NH₄)₃PO₄ will be produced by 7.5 g of ammonia.

Explanation:

H₃PO₄ + 3NH₃ → (NH₄)₃PO₄

H₃PO₄: 98 g/mol

NH₃: 17 g/mol

(NH₄)₃PO₄: 149 g/mol

17 g NH₃ _________ 1 mol

7.5 g NH₃ __________ x

x = 0.44 mol NH₃

3 mol NH₃ __________ 1 mol (NH₄)₃PO₄

0.44 mol NH₃ _________ y

y = 0.15 mol (NH₄)₃PO₄

1 mol (NH₄)₃PO₄ ____________ 149 g

0.15 mol (NH₄)₃PO₄ __________ z

z = 22.35 g (NH₄)₃PO₄

What is the atomic number for an element with 6 neutrons and a mass number of 10

Whitepunk [10]

$\bold{\huge{\blue{\underline{Answer}}}}$

$\bold{\underline{ Given :- }}$

Atomic number of an element with 6 neutrons and a mass number of 10

$\bold{\underline{ Let's \:Begin}}$

$\sf{We\: know\: that, }$

Atomic number is the number of protons in the nucleus of an atom

$\sf{Whereas ,}$

Mass number is the sum of protons and neutrons in the nucleus of an atom.

$\sf{We\: have \:number \:of \:neutrons = 6 }$

$\sf{ Mass\: number = 10 }$

$\bold{\underline{Therefore}}$

$\sf{ Mass\: number = Protons + neutrons}$

$\sf{ 10 = Protons + 6 }$

$\sf{ Protons = 10 - 6}$

$\sf{ Protons = 4 }$

$\sf{ Thus, \: the \: number \: of \: protons \: is \:4}$

$\bold{\underline{ Therefore,\:we\:know\:that, }}$

$\sf{ No\: of\: protons = Atomic \:number }$

$\sf{ 4 = Atomic \:number }$

$\sf { Hence, \:atomic\: number\: of\: the\: element\: is\: 4}$

When hcl(aq) and naoh(aq) are mixed in a beaker, the beaker feels warm to the touch. what is known about the enthalpy of this re

Nady [450]

The balanced chemical equation representing the neutralization reaction of hydrochloric acid (HCl) and sodium hydroxide (NaOH),

$HCl (aq) + NaOH(aq) ---> NaCl(aq) + H_{2}O(l) + Heat$

This reaction is exothermic that is it proceeds by the release of heat energy. This heat energy is lost to the surroundings. This is the reason for the warming up of the beaker where the reaction between hydrochloric acid (HCl) and sodium hydroxide (NaOH) takes place. The enthalpy of such reaction will be negative as the reaction is exothermic.
