In order to compute this, we must first take a couple of assumptions of:
1) The laboratory size so we can calculate its volume
2) The number of students working in the lab so we know the total gas produced
Let the lab be
11 m × 9 m × 6 m
The volume then computes to be:
594 m³
We know that
1 Liter is 1 dm³
1 m = 10 dm
1 m³ = 1000 dm³
Therefore, the room volume in liters is:
594,000 Liters
Let there be 30 students in the laboratory
Total gas being produced:
6 × 30
= 180 Liters
This works out to be:
0.03% of Hydrogen by volume
Therefore, there is no risk of explosion given our assumption of size and students.
Answer is: the hydronium ion (H₃O⁺) concentration is greater than hydroxide ion (OH⁻)<span> concentration.
</span><span>Bases (more hydroxide ions than hydronium ions) turn red litmus paper blue and acids (more hydronium ions than hydroxide ions) turn blue
litmus paper red.
</span><span>Acids and bases have opposite properties and have the ability to
neutralize each other. Acids taste sour, give sharp stinging pain
in a wound and react with metals to produce hydrogen gas.</span>
Answer:
synthesis/combination
Explanation:
There are 5 main types of reactions.
combination/synthesis, decomposition, single-replacement, double-replacement, and combustion
synthesis/combination - A+B → AB
Decomposition - AB → A+B
single- replacement - A + BC → AC + B
double replacement - AB + CD → AD + CB
combustion - example - C3H8(g) + 5O2(g) → 3CO2(g) + 4H2O(g)
If you wanted to balance this
the answer would be →
Answer:
Climate change will make plants—and us—thirstier. The combined effects of increased CO2 levels and warmer temperatures will increase water consumption by vegetation. That will lead to water declines in streams and rivers like the Ashepoo River in South Carolina
Explanation:
F. because electronegativity generally increases as you move from left to right across a periodic table, and F is farther right than O
