When two aqueous solutions are mixed together and the temperature of the solution decreases, the reaction is called an endothermic reaction with a positive enthalpy change. Endothermic reaction is when heat is absorbed by the reaction taking place. All endothermic reaction always have a positive enthalpy change.

Bogdan [553]

Answer:

Because energy is conserved, the kinetic energy of a block at the bottom of a frictionless ramp is equal to the gravitational potential energy of the block at the top of the ramp. This value is proportional to the square of the block’s velocity at the bottom of the ramp. Therefore, the block’s final velocity depends on the height of the ramp but not the steepness

of the ramp

The barometric pressure measured outside an airplane at 3 km ( ft) was 524 mmHg. Calculate the pressure in kPa.
NeX [460]

Answer:

69.8609 KPa.

Explanation:

The following data were obtained from the question:

Pressure (in mmHg) = 524 mmHg.

Pressure (in KPa) =?

Thus we can obtain the pressure in KPa as follow:

760 mmHg = 101.325 Kpa

Therefore,

524 mmHg = 524 mmHg × 101.325 KPa / 760 mmHg

524 mmHg = 69.8609 KPa

Thus, 524 mmHg is equivalent to 69.8609 KPa.

vladimir2022 [97]

Answer:

Experimental investigations are the best type of scientific research to demonstrate the relationships between cause and effect because they allow the investigator to actively manipulate variables and control conditions. This change can be measured to gather evidence to back up or refute the relationship between cause and effect.

marishachu [46]

Answer:

3.00 × 10¹¹ g

Explanation:

According to the United States Department of Agriculture (USDA), Texas had 4,015,000 beef cows in 2013. One beef cow produces 205 grams of methane per day. The methane produced by the beef cows in Texas per day is:

4,015,000Cow \times \frac{205gCH_4}{cow \times day} = \frac{8.23 \times 10^{8}gCH_4}{day}

Each year has 365 days. The methane produced by the beef cows in Texas per year is:

\frac{8.23 \times 10^{8}gCH_4}{day} \times \frac{365day}{1y} = 3.00 \times 10^{11}gCH_4
