The diagram below shows four altitude locations on a mountain.
Which of these locations is most likely to experience the least amount of snow?
Location D
Location C
Location A
Location B
According to the diagram shown, location A will receive least amount of snow in the form of precipitation.
What is precipitation?
Precipitation is defined as any liquid or frozen water which forms in the atmosphere and then gets received on Earth.It is one of the most important steps of the water cycle.
Precipitation takes place in form of clouds when water vapor gets accumulated in clouds and they get bigger and heavy, when the clouds become heavy enough they fall to the land in the form of rain.If a cloud is present at higher altitudes , the water present in the clouds freezes and fall to the ground in form of snow,hail.
Precipitation occurs always in case of fresh water because the sea salt does not evaporate with the water.The different types of precipitation are rain, drizzle,snow,snow hail,etc.

The statue of Liberty is made out of copper metal. When it was first constructed, the color of the copper metal was bright burnt orange.
Over time, however, it slowly developed a green color as it was exposed to air. What happened to the statue of liberty?
Explanation:
The green color of the Statue of Liberty was due to the outer surface covered with hundreds of thin copper sheets. Copper reacts with the air to form a patina or verdigis

Maria walked on a beach made mostly of sand. She walked barefoot
on the beach early in the morning, and the sand was cool. When she
walked in the same area in the afternoon, the sand was hot.
Which statement best describes why the temperature of the sand
increased?
The statement that the atoms in the sand were moving more quickly best describes why the temperature of the sand is increased. The relationship between kinetic energy and temperature is explained here.
What is the relationship between kinetic energy and temperature?The temperature of a body is directly proportional to the kinetic energy. The energy acquired by those molecules which are in motion is called the kinetic energy.
The radiation of the sun falls on a number of objects on our surroundings. The objects absorb this energy till afternoon due to which they become hot.
When Maria walked in afternoon, the sand was hot as its particles have gained the kinetic energy due to which they move rapidly from one place to another. So that the sand feels more hot in the afternoon.
Thus the atoms in the sand were moving more quickly best describes the increase in temperature of the sand.

what is the mass of 1.46 mole of zinc?
Answer:Zinc grams to moles
Molar mass of Zinc(Zn) = 65.38 g/mol. This means 1 mol of Zn is 65.38g . To find the number of moles of Zn, we divide the given amount of Zn by the molar mass of Zn. Hence, 1.34 g of Zn contains 0.020 moles of Zinc
Explanation:
1 mole is equal to 6.023 × 10 ²³ molecules. The mass of 1.46 mole of zinc is 1.34 grams.
What do you mean by mole ?The term mole is defined as the amount of substance of a system which contains as many elementary entities.
The mole concept can be used to convert between mass and number of particles.
One mole of any substance is equal to 6.023 × 10²³ units of that substance such as atoms, molecules, or ions. The number 6.023 × 10²³ is called as Avogadro's number or Avogadro's constant.
Molar mass of Zinc(Zn) = 65.38 g/mol.
This means 1 mol of Zn = 65.38g .
To calculate the number of moles of Zn, we divide the given amount of Zn by the molar mass of Zn.
Hence, 1.34 g of Zn contains 0.020 moles of Zinc.

6. Which of the following molecules has a central atom with precisely two unshared
pairs of electrons?
methane, CH4
ammonia, NH3
hydrocyanic acid, HCN
water, H20
CLEAR ALL
Answer:
water, H20
Explanation:
From the given choices, only water has two unshared or lone pairs of electrons in its central atom.
The formula of water is:
H₂O
H is hydrogen with 1 electron
O is oxygen with 8 electrons and 6 valence electrons
To form the covalent bond, the 6 valence electrons are involved. Two out of the 6 bonds with the two oxygen.
The remaining 4 gives the two lone pairs.

1. 2g of calcium carbonate was added to 40 cm3 of hydrochloric acid of concentration 2 moldm-3.
Write a balanced equation for the reaction. (2 mrks)
The balanced equation :
CaCO₃ (s) + 2HCl (aq) → CaCl₂ (aq) + H₂O (l) + CO₂ (g)
Further explanationEqualization of chemical reaction equations can be done using variables. Steps in equalizing the reaction equation:
1. gives a coefficient on substances involved in the equation of reaction such as a, b, or c etc.
2. make an equation based on the similarity of the number of atoms where the number of atoms = coefficient × index between reactant and product
3. Select the coefficient of the substance with the most complex chemical formula equal to 1
CaCO₃ (s) + HCl (aq) → CaCl₂ (aq) + H₂O (l) + CO₂ (g)
Give coefficient :
CaCO₃ (s) + aHCl (aq) → bCaCl₂ (aq) + cH₂O (l) + dCO₂ (g)
Ca, left=1, right=b⇒b=1
C, left=1, right=d⇒d=1
O, left=3, right=c+2d⇒3=c+2d⇒3=c+2.1⇒c=1
H, left=a, right=2c⇒a=2c⇒a=2.1⇒a=2
the equation becomes :
CaCO₃ (s) + 2HCl (aq) → CaCl₂ (aq) + H₂O (l) + CO₂ (g)

In carbon dioxide, London dispersion forces are the only intermolecular forces of
attraction.
a. TRUE
b. FALSE
Answer:
true
Explanation:
CO has two C-O bonds. The dipoles point in opposite directions, so they cancel each other out. Thus, although CO₂ has polar bonds, it is a nonpolar molecule. Therefore, the only intermolecular forces are London dispersion forces.

What effects do winds patterns have on climate
Prevailing winds bring air from one type of climate to another. For example, warm winds that travel over water tend to collect moisture as they travel; the water vapor in the air will condense as it moves into colder climates, which is why temperate coastal areas often receive heavy rainfall.
