Organisms change their behavior in responses to changes in the environment.

All living things can respond to stimuli in the exterior environment, it is a form of energy-light waves or sound vibrations, From what they sense they will make necessary changes to their diet and or where they are located. Such as winter weather which is a type stimuli will cause some animals to start talking.

2. If a gas at 500 mL has a temperature of 45°C, then what is the new volume when the temperature is increased to 65°C? Show you

OLEGan [10]

Answer:

V2= 531.4 ml

Explanation:

T1= 273+45 °C= 318 Kelvin

T2= 273+65 °C= 338 Kelvin

V1= 500ml *( 0.001L/1ml)= 0.5 Liters

V2= $\frac{V1 * T2}{T1}$ = $\frac{0.5 L * 338K}{318K}$ = 0.5314465409 Liters* (1 ml/0.001 L)= 531.4 ml

Answer: 4.74 moles

Explanation:

$2LiBr+Ba\rightarrow BaBr_2+2Li$

Moles of Ba= $\frac{\text {given mass}}{\text {molar mass}}$

Moles of Ba= $\frac{325g}{137g/mol}=2.37 moles$

According to given balanced equation,

1 mole of Barium gives 2 moles of Li

Thus 2.37 moles of Barium gives= $\frac{2}{1}\times 2.37=4.74 moles$

Thus 4.74 moles of lithium will be produced by 135 g of barium.
