Answer:
1) CO₂
2) 0.2551 g
Explanation:
The balanced reactions are:
CaCO₃ + 2HCl → CaCl₂ + H₂O + CO₂
MgCO₃ + 2HCl → MgCl₂ + H₂O + CO₂
1) The gas produced is CO₂.
2) Calculate mass of CaCO₃:
(0.5236 g) (0.4230) = 0.2215 g CaCO₃
Convert to moles:
(0.2215 g CaCO₃) (1 mol / 100.1 g) = 0.002213 mol CaCO₃
Find moles of CaCO₃:
(0.002213 mol CaCO₃) (1 mol CO₂ / mol CaCO₃) = 0.002213 mol CO₂
Convert to mass:
(0.002213 mol CO₂) (44.01 g / mol) = 0.09738 g CO₂
Calculate mass of MgCO₃:
(0.5236 g) (0.5770) = 0.3021 g MgCO₃
Convert to moles:
(0.3021 g MgCO₃) (1 mol / 84.31 g) = 0.003583 mol MgCO₃
Find moles of MgCO₃:
(0.003583 mol MgCO₃) (1 mol CO₂ / mol MgCO₃) = 0.003583 mol CO₂
Convert to mass:
(0.003583 mol CO₂) (44.01 g / mol) = 0.1577 g CO₂
Total mass of CO₂:
0.09738 g CO₂ + 0.1577 g CO₂ = 0.2551 g CO₂
Bulb is the answer because they are very short underground stem encased in thickened fleshy bulb scale.This scale help to store food

MAKE ME THE BRAINEST!!
Specifically, urease catalyzes the hydrolysis of urea to produce ammonia and carbamate, the carbamate produced is subsequently degraded by means of spontaneous hydrolysis to produce another molecule of ammonia and carbonic acid. [1] Urease activity tends to increase the pH of the medium in which it is due to the production of ammonia. It is produced by bacteria, fungi and several higher plants. Urease, functionally, belongs to the superfamily of amidohydrolases and phosphotriesterases. [2]
Answer:
6.) larger diameter of stomatal pores
A) Increased transpiration pull
1.) thicker film of water on surface of mesophyll cells
2.) higher relative humidity in air around leaf
B) decreases transpiration pull
3.) less curvature of water surface on mesophyll cell walls
4.) lower rate of water evaporation from surface of mesophyll cells.
5.) larger air space in leaf interior
C) has no effect on transpirational pull.
Explanation:
- Transpiration primarily occurs through stomatal openings in the leaves. Increasing the diameter or size of these opening would ultimately increase the amount of water escaping from them and therefore, increase the transpiration rate.
- Higher humidity in the air entails the presence of greater number of water vapours in the atmosphere. Since osmotic pressure plays a major role in transpiration, therefore, this decreases the rate of transpiration.
Answer:
Joint legal custody
Explanation:
During separation of parents depending on the jurisdiction, custody can be granted as either physical or legal custody.
Physical custody involves or relates residential care of the child whereas legal involves participation in important decision involving the child.
In cases of Joint legal custody, both parents participate in important decisions with physical custody going to one parent.
