The correct option is B.

Nuclear fission is a type of reaction in which the nucleus of an heavy radioactive element emits charged particles and break down into smaller nuclei. Nuclear fission involves the splitting of the nucleus of an element into smaller nuclei. The reaction can occur spontaneously or it can be made to occur by bombarding the radioactive element with high energy neutrons. The process of nuclear fission is used in America to generate electricity.

sam records the mass of his evaporating dish as 8.365 g. he records the mass of the evaporating dish and the sample of hydrate a

guapka [62]

0.2701 moles of water were evaporated from the sample by the heating process

Mass of evaporating dish = 8.365 g

mass of dish + hydrate = 18.597 g

mass of hydrate = (mass of dish + hydrate) - mass of dish

hydrate = 18.597 - 8.365 = 10.232 g

Mass of dehydrated material = (mass of dish + dehydrate ) - mass of dish

dehydrated material = 18.735 - 8.365 = 5.37 g

Mass of water evaporated = hydrate - dehydrate

mass of water = 10.232 - 5.37 = 4.862 g

Molar mass of water = 18 gm/mol

no. of moles of water evaporated = mass / molecular mass

moles = 4.862/18 = 0.2701 moles

A hiker seals a plastic bag that contains dried fruit before the climbs a mountain. What will most likely happen to the plastic

romanna [79]

From the ideal gas equation,

$PV = nRT$

where n is number of moles, R is Universal gas constant, P is pressure, V is volume, and T is temperature of the gas.

The pressure and volume are inversely proportional to each other at constant temperature and number of moles.

Hence, on decreasing the pressure, the volume will increase.

As the hiker reaches a height of a mountain, the pressure would decrease which results in the reestablishment of equilibrium between gas molecules thus resulting in pushing of bag outwards.

Hence, the bag will expand as the hiker reaches the top of the mountain.
