Answer:
Te
K
Explanation:
Main group elements are elements designated and located on the s-block and p-block on the periodic table. The core group or prominent elements are the elements that make up those groups. These groupings comprise the most naturally rich and abundant elements. The main group elements are those whose characteristics are more predicted as a function of their periodic table location. From the given options, only Te and K are elements of the main-group.
Answer:
1. Source of carbon
2. Removal of cuticle
Explanation:
You may have been doing a photosynthesis lab in a biology course.
1. NaHCO₃
The purpose of creating a sodium bicarbonate solution was to provide the carbon that the plant needs for photosynthesis.
2. Soap solution
The soap solution acted as a detergent. It removed some of the waxy, water-repelling cuticle from the leaf's surface and made it easier for the sodium carbonate solution to get inside.
Answer : 70.906 grams of chlorine reacted with hydrogen
Explanation :
Step 1 : Write balanced chemical equation.
The balanced chemical equation for the reaction between hydrogen and chlorine gas is given below.

Step 2 : Find moles of H₂ gas.
The moles of H₂ can be found as

We have 2.0200 g of H₂ and molar mass of H₂ is 2.02 g/mol.
Let us plug in these values to find moles of H₂.

We have 1 mol of H₂.
Step 3 : Find moles of Cl₂ using mole ratio.
The mole ratio of H₂ and Cl₂ is 1 : 1.
The moles of Cl₂ can be calculated as

Step 4 : Find grams of Cl₂.
Molar mass of Cl₂ gas is 70.096 g/mol
Mass of Cl₂ = 
We have 70.906 grams of Cl₂
Answer:
Decreases
Explanation:
Hope this helps:) Good luck!
