Answer:
Pressure gas A
using boyles law
= 
V2
V2 = 717ml + 179 ml
= 896ml
∴ = 2.50 × 717ml/896ml
= 2.0 bar
Pressure B
P2 = 4.30 bar× 179ml/896ml
= 0.859bar
ptotal = 
+
= 2.0 bar + 0.859 bar
= 2.859 bar
Explanation: Using Daltons law of partial pressure,the pressure is independently of each other when the gas is exerted.where we can use daltons law to find the pressure of each gas separately when it expands into the total volume in two containers.
Answer: Different types of chemical bonds and their varying intensity are directly responsible for some of the physical properties of minerals such as hardness, melting and boiling points, solubility, and conductivity. Chemical bonds also influence such other properties as crystal symmetry and cleavage. Hope this helps :)
Explanation:
Scatter Plots. Scatter Plots show the relationship between two variables.
Answer:
<h2>1. Ionic compound-
</h2><h2>2. Polar molecular compound-
</h2>
Explanation:
Mg is a metal that has 12 atomic numbers and thus its electronic configuration is 
. The outer most shell of this element has 2 electrons so it loses 2 electrons and thus form 
ions. Br is a nonmetal and has 35 atomic number so its electronic configuration is 
. Since its outermost shell has 7 electrons so it can accept one electron and thus forms 
. So magnesium ion and bromide ion combine and forms an ionic compound .
P is also a nonmetal and combine with Br with covalent bond and due to electronegativity differences form polar covalent compound such as .
