Answer:

Let us write down the reaction equations for inorganic substances:

N2 + 3H2 = 2NH3 – redox reaction (ORR), ammonia was obtained;

4NH3 + 5O2 = 4NO + 6H2O – ОВР, nitrogen oxide was formed (2);

2NO + O2 = 2NO2 – ОВР, nitrogen oxide was released (4);

H2O + 2NO2 = HNO3 + HNO2 – OBP, nitric acid obtained;

2HNO3 + PbO = Pb (NO3) 2 + H2O – ion exchange, lead nitrate was formed;

2Pb (NO3) 2 = 2PbO + 4NO2 + O2 – OBP, oxygen was obtained.

The reaction products are of practical importance, for example, lead nitrate is the basis for obtaining pigments necessary for dyeing fabrics in the textile industry. These reactions show the connection of non-metals, hydrides, oxides, acids, salts.

Karo-lina-s [1.5K]

Answer: The law of conservation of mass is reffering to the fact that energy cannot be created or destroyed. So when you speak about atoms not being created or destroyed it is the same thing. Unless you're talking about an atomic bomb where the atoms are split.

One sphere has a radions of 181 cm, another has a radius of 5.01 cm. What is the difference in volume (in cubic centimeters) bet

PSYCHO15rus [73]

Answer:

$2.4*10^{7}cm^{3}$

Explanation:

First you should calculate the volume of a big sphere,so:

$V_{big}=\frac{4}{3}\pi r^{3}$

$V_{big}=\frac{4}{3}\pi (181cm)^{3}$

$V_{big}=2.4*10^{7}cm^{3}$

Then you calculate the volume of a small spehre, so:

$V_{small}=\frac{4}{3}\pi r^{3}$

$V_{small}=\frac{4}{3}\pi (5.01cm)^{3}$

$V_{small}=5.3*10^{2}cm^{3}$

Finally you subtract the two quantities:

$V_{big}-V_{small}=2.4*10^{7}cm^{3}-5.3*10^{2}cm^{3}$

$V_{big}-V_{small}=2.4*10^{7}cm^{3}$

Which of the following scientists was the first to determine the

Maru [420]

Answer:

Robert Boyle

Explanation:

Robert Boyle was an Irish chemist and is famously referred to as the first modern chemist. He was born on the 25th of January, 1627 in Lismore, Ireland and died on the 31st, December 1691, London, United Kingdom.

Robert Boyle was the first to determine the relationship between the pressure and volume of a gas.

Boyles states that when the temperature of an ideal gas is kept constant, the pressure of the gas is inversely proportional to the volume occupied by the gas.

Mathematically, Boyles law is given by;

$PV = K$

$P_{1}V_{1} = P_{2}V_{2}$

Where;

V1 and V2 represents the initial and final volumes respectively.

T1 and T2 represents the initial and final temperatures respectively.
