It is 14, use inverse operations. 41 = 2x+13

The two angles would be both 41 degrees.
$(2x + 13) = 41 \\ 2x = 41 - 13 \\ 2x = 28 \\ x = \frac{28}{2} \\ x = 14$
x in this case would be 14 degrees.

Atoms are made up of protons, neutrons, and electrons.

Energy can be neither created nor destroyed.

Water freezes at 0°C

If a piece of platinum is placed in acid, it will not react.

<h3>What are the correct pairing of the given terms?</h3>

The correct pairing of the given terms are obtained from the given options as follows:

Atoms of elements contains three sub-atomic particles which are protons, neutrons, and electrons.

Energy is the ability to do work.

According to the law of conservation of energy, Energy can be neither created nor destroyed.

Water is a liquid which freezes at 0°C.

Therefore, Water freezes at 0°C.

Platinum is a metal which is less reactive than hydrogen, Hence, it cannot displace hydrogen from acids.

Hence, if a piece of platinum is placed in acid, it will not react.

In conclusion, the correct pairing gives the correct description of the properties of the given terms.

Consider a 100-gram sample of radioactive cobalt-60.

svetlana [45]

It will take 5.2 years to decay.

The half life of cobalt-60 is 5.2 years. The half life is the time taken for the mass of the substance to decrease by a half.

here, the amount of remaining substance is 50%,

so, $(\frac{1}{2} )^{n} = 0.5$

n. log (0.5) = log (0.5)

n = 1

So it would take 1 half lives to decay this much, which is 1 x 5.2 which is 5.2 years.

what do you mean by radioactive decay ?

The process through which an unstable atomic nucleus loses energy via radiation is known as radioactive decay, also known as nuclear decay, radioactivity, radioactive disintegration, or nuclear disintegration. A material that has unstable nuclei is considered as radioactive.

A solution of acetic acid and water contains 205.0 g L-1 of acetic acid and 820.0 g L-1 of water. Compute the density of the sol

LekaFEV [45]

Answer:

$\rho_t=1025000 gmL^{-1}$

Explanation:

From the question we are told that:

Density of acetic acid $\rho_a=205 gL^{-1}$

Density of Water $\rho_w=820 gL^{-1}$

Generally the equation for Solution Density is mathematically given by

$\rho_t= \rho_w+\rho_a$

$\rho_t=205+820$

$\rho_t=1025 gL^{-1}$

$\rho_t=1025000 gmL^{-1}$

Which of the following forms a new substance? melting, evaporating, freezing or burning

Slav-nsk [51]

It would be burning be cause when you freeze, evaporate, or melt anything it is just changing how fast the atoms are moving . Think of it like water, ice, and steam, they are all the same thing but in different forms because of melting, evaporating,and melting. Burning is breaking it down.
