Answer:
The Ionic compound is held by ionic bonding and this ionic bond forms between a metal and a non-metal. Here the calcium atom is the metal and the oxygen atom is a non-metal this set of atoms will form an ionic compound.
Answer:
fruit cake is the right ans
Answer:
22 cubic inches
Explanation:
We are given;
- Mass of titanium = 3.6 pounds
We are required to determine the volume of titanium in cubic inches
- We need to know the density of titanium;
Density of titanium = 4.51 g/cm^3
1 pound = 453.592 g
therefore, 3.6 pound = (3.6 × 453.592 g per pound)
= 1632.93 g
Therefore;
Volume = Mass ÷ density
= 1632.93 g ÷ 4.51 g/cm^3
= 362.069 cm³
But, 1 in³ = 16.387 cm³
Therefore;
Volume = 362.069 cm³ ÷ 16.387 cm³ per in³
= 22.095 in³
= 22 in³
Thus the volume of titanium is 22 cubic inches
Following three <span>things when applied could make the reaction to occur more quickly;
1) Increasing Temperature:
Increase in temperature increases the Kinetic energy of molecules. This results in increase in the velocity and rate of collisions between reactants. Hence, greater the number of collisions between reactants per time greater will be the probability of formation of product per unit time.
2) Grinding Calcite:
Grinding of Calcium carbonate results in the increase of surface area of calcite. So greater the surface area greater is the exposure of Calcium carbonate to HCl molecules, hence the rate of formation of product increases.
3) Using Catalyst:
Very important. Catalyst when used decreases the activation energy and increase the rate of reaction by following methods.
a) Providing new pathway
b) weakening the bonds
c) providing surface area
d) holding up the reactant close to each other.</span>
You could use percent error. Absolute | | of accepted value minus experimental value \ divided by accepted value multiply by 100 and that is your answer
