Slow it down - I believe?
Molecules in the paper react differently with Hydronium and Hydroxide.
pH paper deals with acidity and basicity of something. You are correct in thinking that A is the answer. Always go with your gut. don't be like me when I was in college who always second guessed my answers. Good luck with chemistry.
Answer:
Material is less dense than water so it will float in water.
Explanation:
Given data:
Mass of material = 110 g
Volume of material = 312 cm³
Will it float or sink in water = ?
Solution:
First of all we will calculate the density of material.
d = m/v
d = 110 g/ 312 cm³
d = 0.35 g/cm³
The density of water is 1 g/cm³ it means material is less dense than water so it will float in water.
The correct answer is - landscapes.
Both the compression and the erosion are processes that contribute to the shape and form of the landscape. They are different from one another and create different types of landscape forms. The compression is the one that creates hills, mountain ranges, highlands, and it does that by creating a lot of pressure on the land which gradually lifts it upwards. The erosion, on the other hand, is a process that has the opposite effect. The erosion has a tendency to flatten the landscape. It moves away the sediments broken down by the weathering and gradually makes the landscape flatter. Also it creates numerous interesting shapes in the nature, especially on the places where the wind and the water are the ones responsible for the erosion.
Explanation:
The bigger the mass and the higher the height of the object above earth’s surface, the bigger the potential energy. The potential energy can be evaluated using the formula below;
P.E. = m*g*h, where
m = mass in kilograms,
g = the acceleration due to gravity (9.8 m / s² at the surface of the earth), and
h = height in meters.
From the formula, it is clear that increasing mass, gravity or/and height will give an increased potential energy
