The mass of the liquid is 280 g.
Mass = 200 mL × (1.4 g/1 mL) = 280 g
Answer:
1,300,000,000,000
Explanation:
1.3 x 10^12
We want to convert this from scientific notation.
Tip: in scientific notation the exponent tells you how many place you move the decimal point over. If the exponent is negative you move the decimal point to the left. Ex. For, 4.1 x 10^-8, we would move the decimal point over 8 times to the left to get .00000041. When the exponent is positive we move over to the right. Ex. For, 7.6 x 10^7 we would move the decimal point over 7 times to the right to get 76,000,000
So to convert 1.3 x 10^12 we simply move over the decimal point over 12 times to the right.
1.3 x 10^12 ------> 1,300,000,000,000
Our answer is 1,300,000,000,000
Answer:
Acidic conditions
Explanation:
From the equations, it is clear that addition of acid favours the precipitation of calcium oxalate. As acid is added, the equilibrium position continues to shift to the far right, favouring the complete dissociation of the oxalic acid. This decreases the pH of the solution by increasing oxonium ion concentration.
Similarly, as the oxalate ion concentration increases, the precipitation of the calcium oxalate is favoured at low pH. Hence the answer.
A kelp forest is an ecosystem in itself. Many animals use these massive forests to shelter their young from predators. Other animals feed off of the kelp plants. When you understand how marine life lives with the kelp forests you can begin to understand the big picture.
Answer:
Explanation:
Mole = No. Of atom/Avogadro const
Avogadro constant= 6.02×10^23
Mass of Cu =22g
Molar mass of Cu =63.5g/mol
Mole = mass/molar mass
Mole = 22/63.5
Mole = 0.346
No. Of atom=mloe ×avogadro conts
No. Of atom = 0.346 × 6.02×10^23
No. Of atom = 2.09 × 10^23atoms
