Answer:

A reaction in which the oxidation state of one element increases and another decreases

Explanation:

Redox reaction means both oxidation and reduction take place in that reaction.

So when an element oxides its oxidation state increases and when an element reduces its oxidation state decrease.

A 10.00 g sample of a soluble barium salt is treated with an excess of sodium sulfate to precipitate 11.21 g BaSO4 (M- 233.4). W
aliina [53]

Answer:

The salt is barium chloride.

Explanation:

BaX_2++Na_2SO_4\rightarrow BaSO_4+2NaX

Moles of barium sulfate =\frac{11.21 g}{233.38 g/mol}=0.0480 mol

According to reaction, 1 mol of barium sulfate is produced from 1 mol of BaX_2.

Then 0.0480 moles will be produced from:

\frac{1}{1}\times 0.0480 mol=0.0480 mol of BaX_2.

Mass of BaX_2 used = 10.00 g

Moles of BaX_2 =\frac{10.00 g}{\text{Molar mass}}[/tex]

0.0480 mol=\frac{10.00}{\text{Molar mass}}

Molar mass of BaX_2 = 208.33 g/mol

The nearest answer to our answer is BaCl_2=208.2 g/mol.

The correct answer barium chloride with molar mass of 208.2 g/mol.

Why is creativity important in constructing scientific explanations?
poizon [28]

D. Sometimes it is necessary to put forth new theories to explain  experimental results,

Explanation:

Creativity is important to science because sometimes, it is necessary to put forth new theories to explain experimental results.

Theories are explanation of scientific observations.

  • Most scientists are critical and creative thinkers.
  • They must be able to come up with a wide range of possible explanation to explain their findings.
  • The explanations must be scientific in nature and not fall out of the basic tenets of this way of thinking.
  • Therefore, scientists draw from their wealth of deductive reasoning to give explanations into an observed phenomenon.

4.65 L of nitrogen at standard pressure is compressed into a 0.480 L container. What is the new pressure in kPa?
Semenov [28]
Assuming that nitrogen gas is ideal, we can use the equation PV = nRT to relate first conditions to the second condition. At constant temperature, pressure and volume are indirectly related as follows:

P = k / V

k is equal nRT

P1V1 = P2V2
P2 = 101.325 ( 4.65 ) / .480 = 981.586 kPa
