Dalton believed that:

The reactant side of a balanced chemical equation is shown below.

Tresset [83]

Answer: There are 8 hydrogen atoms on the product side in the reaction.

Explanation:

Every balanced chemical equation follows law of conservation of mass.

This law states that mass can neither be created nor be destroyed but it can only be transformed from one form to another form. This law also states that total number of individual atoms on the reactant side must be equal to the total number of individual atoms on the product side.

For the given reaction, the balance chemical equation follows:

$PCl_5+4H_2O\rightarrow H_3PO_4+5HCl$

On reactant side:

Number of Phosphorus atoms = 1

Number of Chlorine atoms = 5

Number of Hydrogen atoms = 8

Number of Oxygen atoms = 4

On Product side:

Number of Phosphorus atoms = 1

Number of Chlorine atoms = 5

Number of Hydrogen atoms = 8

Number of Oxygen atoms = 4

Hence, there are 8 hydrogen atoms on the product side in the reaction.

An arctic weather balloon is filled with 34.1L of helium gas inside a prep shed. The temperature inside the shed is 5.Â°C. The b

mart [117]

Answer:

When the balloon is taken outside if the outside temperature is lower than the temperature inside the shed, the volume of the helium gas will decrease according to Charles' law. However, if the temperatureoutside is higher than inside the shed, the volume of the helium gas in the weather balloons will increase.

Note: The question is not complete. Assumptionshas been made about the temperature.

Explanation:

According to Charles' law of gases, the volume of a given mass of gas is directly proportional to its temperature in Kelvin provided its pressure remains constant.

Mathematically, V1T1 = V2T2

Given that the volume of the helium gas inside the weather balloon is 34.1 L at a temperature of 5 Â°C;

When the balloon is taken outside if the outside temperature is lower than the temperature inside the shed, the volume of the helium gas will decrease according to Charles' law. However, if the temperatureoutside is higher than inside the shed, the volume of the helium gas in the weather balloons will increase.

Assuming, the temperature outside the shed was 6.5 Â°C:

V1 = 34.1 L, T1 = 5.Â°C or 5.0 × 10^-10 °C = 273.1500000005

V2 = ?, T2 = 6.5 Â°C 6.5 × 10^-10 °C = 273.15000000065

V2 = V1T1/T2

V2 = (34.1 × 273.1500000005) / 273.15000000065

V2 = 34.1 L

Due the very small increase in temperature, the volume of the balloon increases only very slightly that is increase that it is negligible.

26.42m Significant figure

Elan Coil [88]

Answer:

4 sig figs

Explanation:

There are 4 because they are all # 1 or above.

0 has special rules on whether or not it is significant.

0 being between two other sig figs no matter how far apart makes it a sig fig.

example: 101 is 3 sig figs

0 that is at the end of a non decimal number are not significant.

example: 110 is 2 sig figs

0 that are after a decimal are significant as long as they after another sig fig.

example: 1.000 and .1000 are both 4 sig figs

extra examples:

110.01 is 5 sig figs

110.1 is 4 sig figs

.0001 is 1 sig figs

What is the role of a turbine in an electric generator? Question 1 options: It stores energy for later use. It releases chemical

kiruha [24]

Answer:

IT PROVIDES MECHANICAL ENERGY

Explanation:

Turbine is a rotatatory device that provides energy from a working fluid and converts it into mechanical energy useful for the generation of electrical energy when combine with an alternator or generator.

It is used in the production of electricity. It begins from the action of a Reactor which provides energy from large radio-active isotopes as they undergo nuclear fission. The energy produced by the Reactor is used to rotate the turbine which provides the mechanical energy needed to transfer energy from a working fluid to the generator. The generator then provides the electrical energy for transmission.
