Answer:
The answer to your question is 160 g of Calcium
Explanation:
Data
mass of Calcium = ?
mass of Hydrogen = 8 g
reactant = HCl
Process
1.- Write the balanced chemical reaction
Ca + 2HCl ⇒ CaCl₂ + H₂
2.- Look for the atomic number of Calcium and hydrogen
Calcium = 40 g
Hydrogen = 1 x 2 = 2 g
3.- Use proportions to calculate the mass of calcium needed.
40 g of Calcium ---------------- 2 g of hydrogen
x ----------------- 8 g of hydrogen
x = (8 x 40) / 2
x = 320/2
x = 160 g of Calcium
Weight is the force of gravity on an object. Weight depends on the strength of the gravitational field the object is in and the mass of the object. ... Mass is constant anywhere in the universe, whereas weight depends on the gravity where the object is present (Earth, the moon, Jupiter, etc.).
Answer:
No, The equation is not balanced
The correct ans is
2CO+O2=2CO2
Answer:
Plate boundaries are the edges where two plates meet. Most geologic activities, including volcanoes, earthquakes, and mountain building, take place at plate boundaries. ... Divergent plate boundaries: the two plates move away from each other. Convergent plate boundaries: the two plates move towards each other.
