Beyond durability, cockroaches are built to play defense. They have an exoskeleton to protect their soft bodies, and will hide whenever they're in the process of molting their exoskeleton. The exoskeleton is not only rigid but flexible to allow the roach to crawl into tiny crevices. Their legs are built for running
Answer:
3.94 atm
Explanation:
Using the general gas law equation as follows;
PV = nRT
Where;
P = pressure (atm)
V = volume (L)
n = number of moles (mol)
R = gas law constant (0.0821 Latm/molK)
T = temperature (K)
According to the information provided in this question;
P = ?
V = 50 L
T = 300K
n = 8 mol
Using PV = nRT
P = nRT/V
P = (8 × 0.0821 × 300) ÷ 50
P = 197.04 ÷ 50
P = 3.94 atm
The combined mass of rock 1 and 2 = 19.28 + 25.3
= 44.58
Difference between rock 3 and combined rocks
= 46.3 - 44.58
= 1.72 grams
therefore, the third rock was 1.72 grams greater than the combined mass of the other two rocks.
Answer:
Clay is not mined in Minnesota.
Explanation:
- Minerals that are found in Minnesota are broadly categorized into two types- metallic minerals and industrial minerals.
- Metallic minerals divided into ferrous mineral which contain iron and non ferrous minerals donot contain iron but it contain other metals like copper.
- Metallic minerals contain iron ore,where as non ferrous minerals contain manganese,copper,nickel,platinum,titanium etc.
- Industrial minerals include sand,gravel,peat,landscape stone,silica sand,limestone, china clay etc.
- Some times,different bedrock are mined like quartzite, granite, gabbro, gnesis etc.
