The answer would be 560,848,164 because the 0 at the start WOULDNT matter
Answer:
<em> 14, 508J/K</em>
ΔHrxn =q/n
where q = heat absorbed and n = moles
Explanation:
<em>m = mass of substance (g) = 0.1184g</em>
1 mole of Mg - 24g
<em>n</em> moles - 0.1184g
<em>n = 0.0049 moles.</em>
Also, q = m × c × ΔT
<em> Heat Capacity, C of MgCl2 = 71.09 J/(mol K)</em>
<em>∴ specific heat c of MgCL2 = 71.09/0.0049 (from the formula c = C/n)</em>
<em>= 14, 508 J/K/kg</em>
ΔT= (final - initial) temp = 38.3 - 27.2
= 11.1 °C.
mass of MgCl2 = 95.211 × 0.1184 = 11.27
⇒ q = 11.27g × 11.1 °C × <em>14, 508 j/K/kg </em>
<em>= 1,7117.7472 J °C-1 g-1</em>
<em />
<em>∴ ΔHrxn = q/n</em>
<em>=1,7117.7472 ÷ 0.1184 </em>
<em>= 14, 508J/K</em>
Answer:
Single-gene disorders, where a mutation affects one gene. Sickle cell anemia is an example.
Chromosomal disorders, where chromosomes (or parts of chromosomes) are missing or changed.
Complex disorders, where there are mutations in two or more genius.

Answer:
The pressure will be 0,37 atm.
Explanation:
We use the Boyle Mariotte´s formula,where for a given mass of gas, at constant temperature, the pressure and temperature vary inversely proportionally. We see here that the initial and final temperature does not vary (298K).
We convert the unit Celsius into Kelvin (0 ° C = 273K) and the unite mmHg into atm (760mmHg=1 atm):
25°C= 25+273=298K ; (1060mmHgx 1 atm)/760mmHg)=1,39 atm.
We convert unit of volume from ml to L: 174/1000=0,174L and 650/1000=0,650L
P1xV1= P2xV2
1,39 atm x 0,174L =P2 x0,650L
P2= (1,39 atm x 0,174L)/0,650L= 0,37 atm
Filtration is useful for separating sediments that are carried in water for easy drinking without the risk of disease - an example of this is a water purifier
