Your answer would be, The lower the group number, the lower the period numbers, therefore, metalloids are found in a diagonal moving down from left to right.
Hope that helps!!!
Answer:
The dynamic viscosity of the liquid is 0.727 kg/m*s
Explanation:
In the equation for that viscosimeter, ν = KR⁴t, <u>the terms K and R are not dependent on the liquid that is being tested</u>, unlike ν and t.
Using that equation and the data given in the problem, we can calculate the product of K and R⁴.
1.19*10⁻³m²/s = (KR⁴)* 1430 s
KR⁴=8,32*10⁻⁷m²/s²
We can now calculate the<em> </em><u><em>kinematic</em></u> viscosity of the unknown liquid.
ν=8,32*10⁻⁷m²/s²*900s
ν=7.49*10⁻⁴m²/s
The relationship between the <em>kinematic</em> viscosity and the <em>dynamic</em> viscosity is given by the equation μ=ν * ρ, where μ is the dynamic viscosity and ρ is the density. Thus:
μ=7.49*10⁻⁴m²/s * 970 kg/m³
μ=0.727 kg/m*s

Explanation:
hello
Al(s) + 2AgNO3(aq) = Al(NO3)3(aq) + 3 Ag (s)
is a single replacement reaction
A single replacement reaction is a type of chemical reaction were element react with a compound and the element take place of another element in that compound. In the reaction above Aluminium (Al) take the place of silver (Ag) from it compound.that is AgNO3. single replacement reaction is possible because aluminium is in high in reactivity series as compared to silver.
Answer:
Q = 2997.69 J
Explanation:
Given that,
The mass of ice, m = 15.6 grams
The temperature increases from -8.76 degrees Celsius to 85.9 degrees Celsius.
The specifc heat of ice is 2.03 J/g°C
We need to find the amount of energy required. The formula for energy required is given by :
So, the required heat is equal to 2997.69 J.
