When the pH falls below 7.35, <span>a state of acidosis exists.
</span>The normal pH in the mammals arterial blood is between 7.35 and 7.50, so a<span>cidosis occurs when arterial </span>pH falls below 7.35. Acidosis is a process causing increased acidity (<span>increased </span>hydrogen ion or proton H⁺ concentration) in the blood and other body tissues.
Alkalosis<span> occurs at a pH over 7.45.</span>
Answer:
317.6 mL
Explanation:
Step 1: Write the balanced neutralization equation
MgO + 2 HCl ⇒ MgCl₂ + H₂O
Step 2: Calculate the mass corresponding to 640.0 mg of MgO
The molar mass of MgO is 40.30 g/mol. The moles corresponding to 640.0 mg (0.6400 g) of MgO are:
0.6400 g × (1 mol/40.30 g) = 0.01588 mol
Step 3: Calculate the moles of HCl that react with 0.01588 moles of MgO
The molar ratio of MgO to HCl is 1:2. The moles of HCl are 2/1 × 0.01588 mol = 0.03176 mol
Step 4: Calculate the volume of 0.1000 M HCl that contains 0.03176 moles
0.03176 mol × (1 L/0.1000 mol) = 0.3176 L = 317.6 mL
Answer:
15.75g
Explanation:
Rearrange the formula: density = mass/volume, so that mass is the subject: mass = density × volume
Now substitute (plug in) the known values into the formula:
mass = 10.5 × 1.5 ⇒ mass = 15.75g
The mass of the silver necklace is 15.75g
Hope this helps!
Always is a pretty absolute word and since nothing is impossible I would say no. However, usually for the most part technology does follow science.
If you want to develop a technology, you need to understand the physical principals behind it such as dynamics,material behavior, etc. this all requires knowledge physics and chemistry.

Physicists during the 1800's were studying the theory to magnetic and electric fields and their interactions way before they were devices to create/observe this phenomenon esp. according to their theory.</span><span>
