A.Background of the Study

Explanation:

Background information identifies and describes the history and nature of a well-defined research problem with reference to the existing literature. The background information should indicate the root of the problem being studied, appropriate context of the problem in relation to theory, research, and/or practice, its scope, and the extent to which previous studies have successfully investigated the problem, noting, in particular, where gaps exist that your study attempts to address. Background information does not replace the literature review section of a research paper; it is intended to place the research problem in a proper context.

C.SIGNIFICANCE OF THE STUDY

The significance of the study is basically a written statement that "explains why your research was important". It justifies why your research was needed, the impact of your research in your field, its contribution, and how others (audience) would benefit from it.

Problem:

What pressure will 37.18 grams of co2 exert in a container at standard temperature?

We to Convert grams to moles of CO₂

1 mole of CO₂ is equal to  44.01 g

37.18 gram / 44.01 g = 0.84 mol

Given Data:

V (volume) = 22.4 L (in STP)

T (temperature) = 273.15 K (in STP)

n (amount of gas in moles) = 0.84 mol   or 37.18 grams

R (gas constant) = 0.0821 atm.L / mol.K

P (pressure) = ? unknown

Solution:

We can use the formula PV=nRT, and to solve for P we will use P = nRT/V

P = nRT/V

= 0.84 mol × 0.0821 atm.L / mol.K × 273.15 K / 22.4 L

= 18.8375166 atm / 22.4

= 0.84 atm

Pressure is 0.84 atm

Given:

_Bi(NO₃)₃  + _CaI₂     ⇒    _ BiI₃    +  _Ca(NO₃)₂

The type of chemical reaction is double displacement in which cations in both compound of the reactant switch places in the product.

To Balance the chemical equation:

2Bi(NO₃)₃  +  3CaI₂    ⇒   2BiI₃   +  3Ca(NO₃)₂                          ↓                                        ↓                    Reactant                           Product                      Bi = 2                                 Bi = 2                     Ca= 3                                 Ca= 3                      I  = 6                                    I = 6                   NO₃ = 6                              NO₃ = 6

We balance the chemical equation since atoms are not destroyed in the process and the mass is conserved. The mass of the reactant is equal to the mass of the product which also means, the number of atoms of elements in both the product and reactant are equal.

Hope it helps=)
