Alright sorry you're getting the answer hours later, but i can help with this.
so you're looking for specific heat, the equation for it is <span>macaΔTa = - mbcbΔTb with object a and object b. that's mass of a times specific heat of a times final minus initial temperature of a equals -(mass of b times specific heat of b times final minus initial temperature of b)
</span>so putting in your values is, 755g * ca * (75 celsius - 84.5 celsius) = -(50g * cb * (75 celsius - 5 celsius))
well we know the specific heat of water is always 4180J/kg celsius, so put that in for cb
with a bit of simplification to the equation by doing everything on each side first you have, -7172.5 * ca = -14630000
divide both sides by -7172.5 so you can single out ca and you get, ca= 2039.74
add units for specific heat which are J/kg celsius and the specific heat of the material is 2039.74 J/kg celsius
Answer:
Yes because the law of conservation of matter is followed. There are equal numbers of atoms of all elements in the
reactants and products.
Explanation:
A balanced equation conform to the law of conservation of matter. While unbalanced equation suggests that matter has been created or destroyed.
Na3PO4 + 3KOH —> 3NaOH + K3PO4
A careful observation of the above equation proved that the equation is balanced is balanced because there are equal numbers of atoms of all elements in the
reactants and products.
Sublimation.
Since evaporation is liquid into gas, melting is solid into liquid and deposition is the geological process where sediments are added to land forms.
