Surface Winds
“During an El Niño year, weakening winds along the equator lead to warming water surface temperatures that lead to further weakening of the winds.” The image below shows the dominant direction of the winds and changes in their intensity near the ocean surface as observed by NASA's RapidScat instrument.

How could you use two beakers distilled water two hot plates two thermometers and salt to test if adding salt affects the boilin
ICE Princess25 [194]
You are given two beakers, distilled water, two hot plates, two thermometers and salt. These materials are enough in order to test the effect of salt in the boiling point water. To do this, you set up two beakers. In one of the beakers, you add pure distilled water and nothing else. For the other beaker, you put a solution of salt and water. You place these beakers on separate hot plates and place inside the beakers the thermometers. You heat these substances until they boil and then you measure the boiling points of the substances. You would observe that the boiling point of the solution would have a higher boiling point than the pure liquid.

Why do we have to balance chemical equations
Lunna [17]

Answer:

  • <em>Chemical equations are balanced </em><u>to comply with the law of conservation of mass.</u>

Explanation:

Law of conservation of mass states that matter cannot be either created or destroyed.

A skeleton chemical equation shows the reactants and products of a chemical reaction without taking into account the real proportion in which the reactants combine and the products are obtained.

An example of a skeleton reaction is the combustion of methane:

  •    CH₄ + O₂ → CO₂ + H₂O

Such as that equation is shown, there are four atoms of hydrogen in the reactants but only 2 atoms of hydrogen in the products. Also, there are 2 atoms of oxygen in the reactants but three atoms of oxygen in the products. This seems to show that some atoms of hydrogen have been destroyed and some atoms of oxygen have been created. This is impossible as it is against the law of conservation of matter.

Then, to show a real situation, the chemical equation of combustion must be balanced, adjusting the coefficients. This is the balanced chemical equation:

  •    CH₄ + 2O₂ → CO₂ + 2H₂O

Now you see that the number of atoms of each matter is conserved: the number of carbon atoms in each side is 1, the number of atoms of hydrogen in each side is 4, and the number of atoms of oxygen in each side is 4. Thus, by balancing the chemical equation, the law of conservation of mass is not violated.

Cubes are three-dimensional square shapes that have equal sides. What is the density of a cube that has a mass of 12.6 g and a m
ratelena [41]

Answer:

A.  0.1828 g/cm³

Explanation:

Hi there,

Density's well known formula is Greek letter rho:   ρ =\frac{m}{V}= \frac{m}{a^3}    where m is the mass, and V is volume. Since the volume in question is a cube, the volume of a cube is simply the edge length V = a³

V = (4.1 cm)³ = 68.921 cm³

ρ = \frac{12.6 g}{68.921 cm^3} = 0.1828 g/cm³

Thanks,

Is it true that we always see the same face of the Moon. <br> Yes<br> No Maybe
Hoochie [10]

Answer: no

The moon orbits the Earth, and the Earth orbits the Sun, so we do not see the same part of the moon. We always see different parts of it.

Hope this helps you!
