Answer:
2NaOH+H2SO4 Na2SO4+H2O the equation is balanced/unbalanced because the number of hydrogen atoms and oxygen/sodium is equal/not equal in the reactants and in the products.
Explanation:
<span>Let F be the maximum thrust of the car's engine. Then F = ma = 1300 x 3.0 = 3900N. With the added load, F remains the same, but we now have F = 1700a giving a = F/1700 = 3900/1700 = 2.3 m/s².</span>
Answer:
ρm=4.14g/ml :metal density
Explanation:
Conceptual analysis
We apply the formula to calculate the density:
ρ= m /V Formula (1)
Where:
ρ:density in g/mL
m: mass in g (grams)
V= volume in ml (milliliters)
Known data
: final volume of liquid=55.25 ml
: final volume of liquid=61.00 ml
ms: metal mass=23.795 g
Problem development
The volume of the metal (vm) is equal to the change in volume of the liquid.
We replace the data in formula (1 )to calculate the density of the metal(ρm):
ρm= mm /Vm=23.795 g/5.75ml
ρm=4.14g/ml
The answer to this question is the "Gay Lussac's Law". This law stated that the pressure and temperature is directly related to each other such that when the pressure increases, the temperature will also increase and vise versa, in short they are directly related. This explanation can be expressed as P1 / T1 = P2 / T2.
