An air mass that forms over Texas will be a ____?Question 1 options:

continental polar air mass

continental tropical air mass

maritime polar air mass

maritime tropical air mass

Answers

Answer 1

Answer:

Answer: continental tropical air mass

Explanation:

The continental tropical mass of air forms over the Texas. It forms in the interior of the subtropical continents at about 150 to 350 North to South latitude. They can be characterized by the dry and hot air masses due to the temperature and moisture present in their source region. The tropical air masses originate in the tropical regions (warm regions) these typically have low air pressure.

Answer 2

Answer:

Answer:

Explanation:

continental tropical air mass

The molecular formula of a compound used for bleaching hair is H2O2. calculate (a) mass of this compound that would contain 2.5 moles (b) no of moles of this compound that would exactly weight 30 get.

Answers

The RFM (Relative Formula Mass) of the substance H2O2 is:
H2 = 1 x 2
= 2
O2 = 16 x 2
= 32

32 + 2 = 34

USE THIS FORMULA:

*Mass = Moles x RFM*

Part A:

Mass = Moles x RFM
     = 2.5 x 34
   = 85 g

(You can always rearrange this formula to suit the question)

Part B:

Moles = Mass/RFM
      = 30/34
   =0.8823529........ (Need a calculator haha)
   =0.88 (Rounded up to 2 decimal places)

I hope I helped, ask if you have any questions.

What mineral is this? Irregularly shaped, white with nonmetallic luster, the hardness of 2.5, shows cubic cleavage and dissolves easily in water.

Answers

Answer:

The material we are talking about would be serpentine.

Explanation:

This material is available in two colours green or white and it has a hardness that amounts to 2.5. This material has a luster that is nonmetallic and more of waxy in nature.

This feature becomes Satiny when Nature of is material is Fibrous. This material is used as an insulating material against electricity as well as heat. The property of this mineral is very close to asbestos and is used when prevention from heat and electricity is required.

Answer:

Halite

Explanation:

Halite is the mineral which is called as Rock salt shows cubic cleavage

Halite forms clear transparent crystals with perfect cubic cleavage. Halite is Table salt, the salt is an array of small cubic fragments, the result of halite’s crystal structure and perfect cubic cleavage

Cubic cleavage can be produced by breaking the sample. Halite is one of the few common minerals that, when broken into small fragments, will readily dissolve in water.

Are producers heterotrophs or autotrophs?

Answers

Answer:

Autotrophs

Explanation:

Autotrophs make their own food, or produce food for themselves through the process of photosynthesis. Therefore, we can say that autotrophs are also producers. Some examples of producers are plants, algae, and some types of bacteria.

Consider this equilibrium for a buffer solution: CH3COOH + H2O CH3COO- + H3O + . When a small amount of acid is added to this system, which statement is true when equilibrium is reestablished? A. [CH3COO-] and pH have both increased. B. [CH3COOH] and pH have both decreased. C. [CH3COO-] has decreased and pH remains relatively constant. D. [CH3COOH] has decreased and pH remains relatively constant. E. [CH3COO-] has increased and pH remains relatively constant.

E. [CH3COO-] has increased and pH remains relatively constant.

What kind of buffer would be a mixture of CH3COOH and CH3COONa?

acidic buffer

A mixture of a weak acid and its salt with a strong base serves as an acidic buffer. The reaction shows that some acetic acids react with the OH– from the base and converts it to water.
