1. What is the atom name(s) of Hydrogen Gas, Salt (Sodium Chloride), Methane, Carbon Dioxide, Oxygen Gas, Air, Water, Hydrochloride Acid, Sodium Hydroxide (lye), Carbonated Water?
A 191 mL sample of a 1.3 M sucrose solution is diluted to 500 mL. ▼ Part A What is the molarity of the diluted solution?
To what volume should you dilute 35 mL of a 12 M stock HCl solution to obtain a 0.500 M HCl solution?
A substance is characterized by the thermodynamic data below. Using this, determine the amount of heat (in kJ) required to warm 125.0 grams of the substance from 73.1°C to its boiling point, and then completely vaporize it (phase change).
The Jet Propulsion Laboratory has detected an NEO that is headed toward Earth. The PDCO needs to issue a press release to warn those who will be affected by the asteroid. Using the data gathered by JPL in the table, create a press release to inform the public about: Characteristics of the asteroid The asteroid’s velocity in kilometers per day The asteroid’s kinetic energy in kg⋅km2/day2 The asteroid’s force, once it enters the atmosphere and is affected by Earth’s gravity How this situation compares with the impact of the asteroid at Chicxulub, Mexico, 65.5 million years ago Data Gathered by Jet Propulsion Laboratory, NASA: Asteroid name: 2018 MP34 Mass = 1.6×1011 kg Diameter = 0.49 km Time from Detection (days) Distance from Earth 0 24.6×106 km 2 20.2×106 km 5 13.6×106 km 6 11.6×106 km Write the answer for velocity and once your finished. write a press release about it
A hockey puck slid across an ice rink in 6seconds. It slid from the center line to the goal line in half of that time at 9meterspersecond. What is the distance that the puck slid between the two lines?
What is the pOH of the final solution when 100 mL of 0.20 M NaOH is mixed with 50 mL of a 0.40 M solution of RbOH?
Given the equation: C2H6 (g) + O2 (g) → CO2 (g) + H2O (g) (not balanced) Determine the number of liters of CO2 formed at STP when 891.6 grams of C2H6 is burned in excess oxygen gas. Your answer should be numerical and neglect units (e.g., if you calculate 3.5L then input 3.5).
1) H2(g)+I2(g)⇌2HI(g). Why does the reaction occur only in the forward direction at first? 2) During the reaction, how does the rate of the forward direction compare to the rate of the reverse direction?
