How do I write 0.03438 m in scientific notation using 3 digits?

I just pulled up to Sheetz and filled my car up with gas. Explain the transfer of energy that would occur once I start then drive my car--consider the type of energy that exists within the gas molecules, explain the transfer of form of energy as gas

What type of reaction is shown below? Check all that apply. 2Mg+O2→2MgO synthesis decomposition combustion

Consider the following equilibrium for nitrous acid, HNO2, a weak acid: HNO2 (aq) + H2O (l) - >< - H3O + (aq) + NO2^ - (aq) In which direction will the equilibrium shift if NaOH is added?

Why is it reasonable to assume the specific heats of naoh and hcl solutions are the same as water?

If, at a given temperature, the equilibrium constant for the reaction H2 (g) Cl2 (g) 2HCl (g) is Kp, then the equilibrium constant for the reaction HCl (g) (1/2) H2 (g) (1/2) Cl2 (g) can be represented as:

What does the dashes line represent? A. Medium B. Boundary C. Normal D. Incident Ray

Only a small amount of cerium oxide nanoparticles is needed because the nanoparticles ... 1) are elements 2) are very reactive 3) have a high surface area to volume ration

Describe the solubility of water compared to ethanol?

When the free-energy change (AG) of a reaction is negative, the reaction is said to be: Endergonic Non spontaneous Spontaneous Endothermic

The solubility of carbon dioxide gas in water can be increased by
