Answer:

46.32 mL

Explanation:

We'll begin by writing the balanced equation for the reaction. This is illustrated below:

2HNO₃ + Ca(OH)₂ —> Ca(NO₃)₂ + 2H₂O

From the balanced equation above,

The following data were obtained:

Mole ratio of the acid, HNO₃ (nA) = 2

Mole ratio of the base, Ca(OH)₂ (nB) = 1

Next, we shall write out the data obtained from the question. This includes:

Molarity of the acid, HNO₃ (Ma) = 0.181 M

Volume of the base, Ca(OH)₂ (Vb) = 25.1 mL

Molarity of the base, Ca(OH)₂ (Mb) = 0.167 M

Volume of the acid, HNO₃ (Va) =?

Finally, we shall determine the volume of the acid, HNO₃ as shown below:

MaVa/ MbVb = nA/nB

0.181 × Va / 0.167 × 25.1 = 2/1

0.181 × Va / 4.1917 = 2

Cross multiply

0.181 × Va = 4.1917 × 2

0.181 × Va = 8.3834

Divide both side by 0.181

Va = 8.3834 / 0.181

Va = 46.32 mL

Therefore, the nitric acid, HNO₃ required for the reaction is 46.32 mL

When atmospheric pressure decreases, the mercury height in a barometer

Free_Kalibri [48]

Answer:

Decreases

Explanation:

The atmospheric pressure on the surface of the mercury pushes it up the evacuated tube until the downward pressure of the mercury equals the atmospheric pressure.

If the atmospheric pressure decreases, the mercury doesn't have to rise as high.

The mercury height decreases.

How many atoms of hydrogen are in 0.56 mol of (NH4)2SO4

BabaBlast [244]

<h2>Answer: $2.7\times 10^{24}$ atoms</h2>

Explanation:

The given formula of the compound is $(NH_{4})_{2}SO{4}$

The formula says

Every mole of $(NH_{4})_{2}SO{4}$ contains $8$ moles of atoms of hydrogen.

Given that number of moles of compound is $0.56$

So,the number of moles of hydrogen atoms present is $0.56\times 8=4.48$

Since each mole has $6.022\times 10^{23}$ atoms,

$4.48$ moles has $4.48\times 6.022\times 10^{23}=2.7\times 10^{24}$ atoms.

What does it mean for a element of a group to have a order?

lisabon 2012 [21]

In group theory, a branch of mathematics, the term order is used in two unrelated senses:

<span><span>The order of a group is its cardinality, i.e., the number of elements in its set. Also, the order, sometimes period, of an element a of a group is the smallest positive integer m such that <span>am = e</span> (where e denotes the identity element of the group, and am denotes the product of m copies of a). If no such m exists, a is said to have infinite order.</span><span>The ordering relation of a partially or totally ordered group.</span></span>

This article is about the first sense of order.

The order of a group G is denoted by ord(G) or | G | and the order of an element a is denoted by ord(a) or | a |.
