Sleet is a type of precipitation that is formed by water and snow that is usually partially molten.
What is sleet?
Sleet consists of icy raindrops that hit the surface, that is, part of the precipitation is frozen and the other forms water droplets.
Characteristics of sleet precipitation
The term precipitation refers to water in any form that falls from the sky, sleet is a kind of solid precipitation that occurs at some stage in winter.
Sleet is formed by freezing raindrops or partially melted snowflakes as they fall through a layer of cold air.
Therefore, we can conclude that sleet is a form of winter precipitation, in which rain and snow occur at the same time.

The paths that planets follow around the sun are called as orbit, and they are shaped like an ellipse.
What is orbit ?The orbits of the planets around the sun are elliptical. Kepler, an astronomer, provided a clear definition of these orbits. The three rules he created are referred to as Kepler's laws of planetary motion. It says that every planet does an orbit around the sun.
The plane of Earth's orbit around the sun serves as the definition of the ecliptic. The primary planets of our solar system, their moons, some asteroids, and their orbits all roughly follow this plane.
An orbit is a curved path taken by an object, such as a planet's path around a star, a natural satellite's path around a planet, or a man-made satellite's path around a planet, moon, or asteroid.
Thus, the paths that planets follow around the sun are called as orbit.

The correct answer is option A, that is, HCl.
An acid refers to an ion or molecule possessing the tendency of donating a hydrogen ion or a proton, or alternatively, exhibiting a tendency of producing a covalent bond with a pair of electrons. The aqueous Arrhenius acids exhibit characteristic features that offer a practical illustration of an acid.
The acids can turn blue litmus paper red, can form aqueous solutions with a sour taste, and reacts with bases and some kind of metals to produce salts. One of the general aqueous acids is HCl (hydrochloric acid) that is found in the stomach and stimulates digestive enzymes.

Saliva, produced by glands in the mouth, plays an important role in the digestion of food. Saliva contains a chemical, called amylase, that breaks down starch in the food we eat. A scientist conducts an experiment to investigate at which temperatures amylase works the best. He hypothesizes that the reaction will occur fastest if the amylase reaction is conducted near the normal human body temperature of 37ºC (degrees Celsius). In order to test his hypothesis, the scientist measures the reaction rate, which is how fast the amylase breaks down the starch at six different temperatures. The reaction rate is rated on a scale of 0 to 10, with 0 meaning no reaction and 10 meaning the fastest reaction. The results are recorded in the data table.
AMYLASE REACTION RATE BY TEMPERATURE

Reaction Rate

20 4
40 10
60 8
80 2
100 0
Based on the data, should the scientist accept or reject his hypothesis?
Answer:
The digestive functions of saliva include moistening food, and helping to create a food bolus, so it can be swallowed easily. Saliva contains the enzyme amylase that breaks some starches down into maltose and dextrin. Thus, digestion of food occurs within the mouth, even before food reaches the stomach.

Suppose you have samples of three unknown solids. Explain how you could use their properties to determine whether or not they are ionic solids.
Given a sample of three unknown solids, we would be able to deduce which are ionic solids by their melting and boiling points, conductivity in water, and the insulation they provide.
What are Ionic solids?An ionic solid is a solid formed by ionic bonds. They are the solid version of ionic compounds, which are held together by strong electrostatic energies. What properties do they possess?Among their many properties, ionic solids possess high melting and boiling points.These solids are also known to conduct electricity well when dissolved into water, however, this can be tested after melting them as they will not conduct electricity in a solid state.A final property that we can use to identify them is that they provide a good means of insulation.Each of these properties can be tested and will allow us to determine the ionic solids amongst the samples.Therefore, we can find the ionic solids amongst the samples by testing their melting and boiling points, conductivity in water, and the insulation they provide, given that each of these should provide high values to indicate an ionic solid.

Copper has a density of 8.96 g/cm^3. What is the mass of a piece of copper with a volume of 2.62 cm^3?
Answer:
23.48
Explanation:
Good Luck!
Answer: 23.48 g
Explanation:
formula: mass = density x volume
Volume of copper = 2.62 cm^3
Density of copper = 8.96 g/cm^3
mass = 8.96 x 2.62 = 23.4752

Ammonia is manufactured from nitrogen and hydrogen by the Haber process.
N2(g) + 3H2(g)2NH3(g)
What is the percentage yield when 60 kg of ammonia is produced from 60 kg of hydrogen?
A
5.9%
B
17.6%
с
35.3%
D
50.0%
Answer:
B
17.6%
Explanation:
1. Percentage yield = (Actual yield/theoretical yield) x 100
2. You know actual yield of ammonia (60kg) so you need to work out theoretical yield.
3. mols of hydrogen = m/mr = 60,000/2 = 30,000 mols.
4. 3:2 ratio so (30,000/3) x 2 = 20,000 mols of Ammonia.
5. Therefore mass of ammonia = mr x mols = 20,000 x 17 = 340,000 grams
6. So percentage yield is (60,000/340,000) x 100 = 17.6
