Answer : The temperature in Kelvin is, 290 K

Explanation :

S.I : It is known as the international System of Units. It is defined as a scientific method to express the magnitude of the several basics units.

There are seven basic units in the system from which the other units are derived.

The seven base unit are, meter for length, kilogram for mass, second for time, ampere for current, kelvin for temperature, mole for amount of substance and candela for intensity.

The conversion used for the temperature from degree Celsius to Kelvin is:

$K=273.15+^oC$

where,

$K$ = temperature in Kelvin

$^oC$ = temperature in centigrade

As we are given the temperature in degree Celsius is, 17

Now we have to determine the temperature in Kelvin.

$K=273.15+^oC$

$K=273.15+(17^oC)$

$K=290.15K\approx 290K$

Therefore, the temperature in Kelvin is, 290 K

One half of a balanced chemical equation is shown. 3Mg(OH)2 + 2H3PO4 Which lists the numbers of each atom the other half of the

andre [41]

Answer:

3 Mg, 2 P, 14 O, 12 H

Explanation:

Without mincing words, let us dive straight into the solution for the problem above. This question is all about how how equations showing chemical reactions are being balanced.

From the question, we are giving the reactants: which are Mg(OH)2 and H3PO4 and in order to balance the reaction, the number of atoms in the reactants must be equal to the number of atoms in the products side of the reaction. Since, we have 3 Magnesium atoms, 2 Phosphorus atoms, 14 Oxygen atoms, and 12 Hydrogen atoms in the reactants side of the equation, the same number of atoms is expected in the products side.

Two hundred kg of liquid contains 30% butane, 40% pentane, and the rest hexane (mass %) Determine: The mole fraction composition

OlgaM077 [116]

Answer:

The mole fraction composition of the liquid is :

Mole fraction of butane, pentane and hexane are 0.3638,0.3908 and 0.2454 respectively.

Explanation:

Mass of the liquid mixture = 200 g

Percentage of butane = 30%

Mass of butane = $\frac{30}{100}\times 200 g=60 g$
