KATRIN_1 [288]

1. a group of resources treated as a single entity that accepts a combination of materials and instructions to add value through a series of operations; may be either automated or manual.

2. a group of cells that have similar structure and that function together as a unit. A nonliving material, called the intercellular matrix, fills the spaces between the cells.

3. a differentiated structure (such as a heart, kidney, leaf, or stem) consisting of cells and tissues and performing some specific function in an organism.

4. a group of organs that work together to perform a certain function in an organism's body.

5.  complex systems of chemical compounds that, through interaction and environment, play a wide variety of roles. Organisms are semi-closed chemical systems. Although they are individual units of life (as the definition requires), they are not closed to the environment around them.

6. the significance of the charge hosted by a particular atom in a molecule becomes obvious

7. an interacting group of various species in a common location

8. an ecological community comprised of biological, physical, and chemical components

9. the variety of life found in a place on Earth

Zepler [3.9K]

Answer:

The relevant equation is:

CaCO₃ + 2HCl → CaCl₂ + H₂O + CO₂

Explanation:

1 mol of calcium carbonate can react to 2 moles of Hydrochloric acid to produce 1 mol of water, 1 mol of calcium chloride and 1 mol of carbon dioxide.

The formed CO₂ is the reason why you noticed bubbles as the reaction took place

How many grams are in 1.70 moles of Ca(NO3)2?
Andru [333]

The number of grams in 1.70 moles of Ca(NO₃)₂ is 384.2 grams

<h3>How to determine the mass of Ca(NO₃)₂</h3>

The mole of a substance is related to it's mass and molar mass according to the following equation:

Mole = mass / molar mass

With the above formula, we can determine the mass of Ca(NO₃)₂ as illustrated below:

  • Mole of Ca(NO₃)₂ = 1.70 moles
  • Molar mass of Ca(NO₃)₂ = 40 + 3[14 + (16 × 3)] = 40 + 3[14 + 48] = 40 + 3(62) = 40 + 186 = 226 g/mol
  • Mass of Ca(NO₃)₂ = ?

Mole = mass / molar mass

1.70 = Mass of Ca(NO₃)₂ / 226

Cross multiply

Mass of Ca(NO₃)₂ = 1.70 × 226

Mass of Ca(NO₃)₂ = 384.2 grams

Thus, the mass of 1.70 moles of Ca(NO₃)₂ is 384.2 grams
