Answer:
-10 m/s2
Explanation:
The acceleration is taken as −10 m/s2
Answer:
B. mass, volume
Explanation:
Density refers to a physical property that is measured using a ratio of mass divided by volume so that two objects of the same size can still have very different density.
Before answering the question, one should first calculate the pH for given concentration of LiOH.
As LiOH ionizes as,
LiOH → Li⁺ + OH⁻
So, the concentration of OH⁻ = [OH⁻] = 0.01
Also,
pOH = -log [OH⁻]
pOH = -log [0.01]
pOH = 2
Whereas,
POH + pH = 14
Or,
pH = 14 - 2
pH = 12
Result:
As pH is greater than 7, so the solution is Basic.
1.9993999057621666 moles
1 mole = 36.46094
Answer:
An alloy is a mixture of two or more metals which is produced with a specific proportion between metals. So, if the proportion is changed the physical characteristic would be changed as well. For example, brass musical instruments are made of brass which is a mixture (an alloy) of zinc and copper in a specific proportion. If you change a proportion, you will change the physical characteristic of brass musical instruments, and a sound they produce will be different.
